THE thing about Tokyo, explains chef Tim Anderson, is that it's so vertical. "It's not just that it's busy on one level, it's busy in three dimensions - it's a bonkers city."

And that applies to the food as much as the architecture, hence why it's the subject of the London-based, Wisconsin-born restaurateur's latest cookbook, Tokyo Stories.

There are physical and geographical layers to Tokyo's food, starting with the eclectic, hi-tech vending machines on the subway; the conbini convenience stores where you can order yakisoba pan (fried noodles in a bun) or rice balls; then the street food, like yakitori (Japanese chicken skewers), tempura and ramen.

Plus there's Japanese home cooking ("Kitchens in Tokyo are very small. You might just have a microwave and a two-ring electric burner," says Anderson), followed by really fine Japanese dining, high-end stuff like kaiseki (multi-course dinners) and sushi, as well as regional foods you can't get unless you go to that region (except you can get it in Tokyo).

"I wanted to get the whole range," says Anderson, who won MasterChef 2011, and who first visited Japan in 2002 after his parents bought him a package tour as a high school graduation present. "I was barely 18, and I remember Tokyo being so crowded and bright and crazy and just with so much going on that I was actually really intimidated by it."

His defining edible memory of the trip is the bewilderment involved in ordering a burger from fast food chain, First Kitchen. "It was just really hard," he says wryly. "Ordering fast food is not as straightforward as you think, there's always options."

Going on to teach English in Japan for two years, he later discovered that the joint's fries - dubbed 'Flavour Potato' - come with amazing little seasoning packets you shake up with your chips, so they taste like soy sauce and butter, or garlic and miso. Anderson's done his own shake-and-season version in the book.

Now 34, he's got something of a handle - as much as it's possible - on Tokyo's madcap culinary landscape, and uses his visits to explore "unusual parts of Tokyo to find different kinds of food".

As such, he's too busy seeking out new things to have a roster of favourite restaurants to revisit. "I mainly only know what ramen shops to go to," says Anderson with a laugh. "And karaoke bars."

His main aim with Tokyo Stories is to convey the diversity of the food available. "You can go to Tokyo, but also go to France," he explains. "There's fantastic French food and Parisian bakeries."

In fact, "there's a lot of everything," he says. Take the city's clashing pizza culture. "There are two schools of pizza in Tokyo," explains Anderson. "The really nice stuff, and then you get the Japanese equivalent of Domino's, and those are good in a different way, because they're so crazy. They'll usually have Japanese-style toppings on them, or there's a trend now for doing Korean barbecue meat on pizza."

Most intriguing of all perhaps are Japan's convenience stores, which Anderson says are "very special". "Sometimes I think they're my favourite thing about Japan generally," he adds.

He says it's down to the fact they are incredibly well run, thanks to a logistics system that means each branch receives multiple deliveries a day, so fresh produce is never sat on the shelf for long.

"And then they're cooking in there too," Anderson buzzes, awed. "You can get fried chicken in the convenience store by the way! They take it out of hot cupboards, but they're cooking throughout the day. They've got little fryers out the back, so when they need to top up the fried chicken, they just make it."

Then there's steamed buns and vats of dashi bobbing with vegetables ("They give you a big bucket with a handle, top up the broth and it's the best thing to eat in the winter"), and bottled ice teas in every flavour.

"They're magical places," Anderson declares. "I didn't pack enough underwear, so I went to the convenience store - got underwear! They have everything you need, they're fantastic."

He makes it sound like you'd struggle to find fault with any of the city's food, whether you nabbed it from a machine between subway stops, or found an Okinawan inspired hole-in-the-wall. "I've been to my fair share of bad ramen shops, it's not like it's a paradise of perfect food everywhere," he concedes, "but it's pretty close."

"There's not a lot of cities where you can just walk in and have a good shot of getting good food, but Tokyo is that place," he says. "It may not be great, but it'll be good."

Whether you cook from the book or not, Anderson just wants people to know that "Tokyo is just an amazing city".

"For me," he muses, "it's like an emotional thing. There's nowhere I feel more drawn to. I want to go there all the time - when I think about it, it almost feels like a tugging feeling."

"It's a mix of nostalgia," Anderson adds, "but also the opposite of that, because there's always something new and exciting."

HIROSHIMA-STYLE OKONOMIYAKI

A hefty layered pancake of noodles and veg.

"Okonomiyaki, the savoury pancake filled with ingredients of the customer's choosing, is mostly associated with Osaka, to the endless ire of people from Hiroshima, who have their own unique style of okonomiyaki. The Hiroshima style is sometimes called 'Hiroshima-yaki' to differentiate it, but nothing annoys Hiroshimaites more than this, as in their view, it's the Osaka style that is the inferior knock-off version.

"I'm not going to get involved in this rivalry, but I will say that Hiroshima okonomiyaki is indeed delicious, especially if you love noodles, like I do," explains chef Tim Anderson, author of new cookbook, Tokyo Stories. "In fact, it's more like layered yakisoba, with noodles, cabbage and toppings griddled separately from the pancake, which takes the form of a thin crepe that gets draped over everything else."

Ingredients:

(Makes 2 okonomiyaki, which is actually likely to be enough for 4 people)

100g plain flour

120ml dashi

3 eggs

1/2 hispi or flat cabbage, finely chopped

100g bean sprouts

150-200g tin of sweetcorn, drained

4 spring onions , thinly sliced

About 40g beni shoga (pickled ginger, available on amazon)

Vegetable oil

6 rashers streaky bacon

200g prepared squid, scored and cut into 1-cm wide strips

2 portions fresh yakisoba/egg noodles (or dried noodles, parboiled)

About 150ml okonomi sauce (available on amazon)

Kewpie mayo (100g mayo, 1/4tsp dashi, 1/4tsp Dijon mustard, salt and white pepper), as needed

A few pinches of aonori (dried seaweed)

A few pinches of sesame seeds

Handful of katsuobushi (dried smoked tuna, available on amazon)

Method:

1. Whisk together the flour, dashi and one egg to form a thin batter. In a separate bowl, toss together the cabbage, bean sprouts, sweetcorn, half of the spring onions and half of the beni shoga. Set the griddle on medium-high heat and add a little oil, spreading it out into a thin layer with a spatula.

2. Use a ladle to pour out two pancakes on the griddle, reserving about a third of the batter in the bowl. Top each pancake with the cabbage mixture, then drizzle the remaining batter on the top of each cabbage pile. Press down on the cabbage pile to flatten it slightly, and cook for about five minutes. Top each cabbage pile with three rashers of bacon, pressing them down, then deftly flip each pile so the bacon is on the bottom and the pancake is on top. Press everything down again.

3. Stir-fry the squid in a separate space on the griddle and add the noodles on top of the squid. Toss them together with about a third of the okonomi sauce, then gather them into a circle the same diameter as each pancake. Transfer the pancake-cabbage pile to the top of each circle of noodles and cook for another five minutes or so (the noodles should be nice and crisp on the bottom).

4. Meanwhile, fry two eggs on the griddle - typically the yolk is broken, but I do like a runny yolk on my okonomiyaki. When the eggs are cooked, transfer them to the top of each okonomiyaki, then cover in okonomi sauce, mayo, aonori, sesame seeds, the remaining beni shoga and spring onions and katsuobushi. Enjoy straight from the griddle, if possible.

MAPO RAMEN - SICHUAN SPICED TOFU NOODLES

A hearty bowl of tastiness.

"So much of Japanese culture has direct, traceable roots in China: Everything from religion and orthography, to tea bowls and noodles. And despite the political issues between the two countries, there's still a lot of positive cultural exchange between them. One of the more interesting examples of this is ramen, a dish that in Japan many still consider Chinese, but that can now be found all over China, sold as a distinctly Japanese dish," explains 2011 MasterChef champ and restaurateur, Tim Anderson.

"Even more complex is the recent trend of 'mapo ramen' in Tokyo: A combination of a traditional Chinese dish (mapo tofu) with a Japanese version of a Chinese dish (ramen), the result of which is very Chinese in terms of flavour, but that wouldn't be found in China. It's a kind of culinary orphan, neither Japanese nor Chinese but also kind of both. But then again, who cares? It's really delicious and that's all that matters."

Ingredients:

(Serves 4)

600g-700g firm or extra firm silken tofu

Water

Big pinch of salt

2tbsp Sichuan pepper

4 dried red Chinese chillies

4tbsp vegetable oil

2 anchovy fillets (optional)

1 bird's eye chilli (or more, to taste), finely sliced

4 garlic cloves, finely sliced

15g piece of ginger root, peeled and finely shredded

300g minced pork

1tbsp preserved black beans

80g doubanjiang (black bean sauce)

1 1/2 tbsp caster sugar

500ml chicken stock

1tbsp sesame oil

1 1/2tbsp cornflour, mixed to a paste with a little water

Worcestershire sauce and/or soy sauce, to taste

4 portions thick ramen noodles

For the garnish:

Small handful of coriander, roughly torn

Sesame seeds, toasted until deep golden brown

Plenty of sansho pepper

Method:

1. Cut the tofu into 2.5-cm (1-in) cubes and bring a pan of water to a low simmer along with the salt. Carefully add the tofu to the salted water and poach for 10 minutes.

2. Remove gently with a slotted spoon. Toast the Sichuan pepper and dried chillies in a dry frying pan until aromatic and beginning to colour, then leave to cool and grind to a coarse powder.

3. Add the oil to the pan and place over a high heat, then add the anchovies, if using, and the bird's eye chilli. Fry for a minute or two, then add the garlic, ginger and pork and fry until the pork is browned. Add the black beans, doubanjiang, sugar and the ground Sichuan pepper and chillies. Cook for a few minutes, stirring often, so the flavours meld.

4. Add the chicken stock and sesame oil and bring to the boil, then stir in some (not all) of the cornflour-water mixture. Let the sauce boil for a few minutes to thicken, stirring continuously; add more cornflour slurry if you want it thicker (it should be quite thick so it clings well to the noodles). Taste the sauce and adjust seasoning with Worcestershire and/or soy sauces. Gently stir in the tofu, using a pushing motion with the back of your spatula and shaking the pan to coat the tofu without breaking it up.

5. Bring a large pot of water to a rolling boil and cook the noodles until al dente. Drain well, then transfer to four bowls. Top with the hot tofu mixture and garnish with the coriander, sesame seeds and sansho.

OMURICE (AKA seasoned rice topped with an omelette - and ketchup!)

"Omurice combines three of my all-time favourite comfort foods into one wonderful dish: Eggs, fried rice and ketchup. It's so simple yet so satisfying, a perfect package of protein, fat and carbs, so cheap and easy to make, and yet so beautiful I'm actually getting a bit teary-eyed just thinking about it," says chef and cookbook author, Tim Anderson.

"Omurice is a dish that says, 'I want you to feel full and content, I want you to get plenty of calories so you grow big and strong, and I want to put a smile on your face, because I love you.' There are restaurants in Tokyo (and probably home cooks) who have applied cheffy techniques to refine omurice, cooking the omelette just so and serving it with demi-glace and that sort of thing.

"But really, omurice doesn't need careful cooking or fine-dining embellishments to make it delicious. In fact, to me that's really the whole point of omurice. Just about anybody can make it, and it will always be delicious even at its most basic."

Ingredients:

(Makes 1 big omurice enough for 1 hungry person, or 2 not-that-hungry persons, or 2 hungry persons who are also eating other things, like miso soup and salad and whatnot)

30g butter

1 banana shallot or small onion, diced

60g shiitake mushrooms, destemmed and diced

1 chicken thigh, boneless and skinless, cut into 1cm cubes (optional)

300g cooked rice (from 150g uncooked; rice that has been chilled in the fridge works best)

Ketchup, to taste, plus extra to serve

Soy sauce, to taste

Salt and pepper, to taste

3 eggs, beaten with 1 tbsp double cream (optional)

Method:

1. Melt half of the butter in a frying pan over a medium heat, then saute the shallot or onion until translucent. Add the shiitake and the chicken (if using) and saute until the mushrooms soften and the chicken is cooked through.

2. Add the rice, breaking up any clumps, and stir in the ketchup, soy sauce, salt and pepper.

3. Meanwhile, melt the remaining butter in a non-stick frying pan over a medium-high heat, then tip in the beaten eggs and season with a little salt.

4. Cook the egg until set on the bottom but still runny on top, then gently fold the eggs over themselves so the runny bit is now in the middle. Scoop the fried rice into a mound on a plate, then tip the omelette onto the top of the rice. Serve with more ketchup, if you like.
