Okonomiyaki, monjayaki and oden
Savoury okonomiyaki are fast gaining currency outside Japan. Restaurants specializing in this pancake-like dish have tables featuring hot plates; sometimes the batter and ingredients are brought out for you to cook yourself. Fillings can vary, but seafood, noodles and veggies are popular choices. Tokyo has its own variant, known as monjayaki; with a far looser consistency than okonomiyaki, this is always a DIY job, though staff will do the necessaries for you if you ask.
A popular winter dish (though available all year round) is oden, large chunks of simmered tofu, daikon (radish), root-vegetable jelly, seaweed, hard-boiled eggs and fishcakes, traditionally eaten with a smear of mustard; oden is best eaten in izakaya, though convenience stores also sell it.
Grilled meats, cutlets and tempura
Yakitori are delicious skewers of grilled chicken, sometimes served alongside other meats, offal and vegetables. Traditionally seen as something of a non-gourmet, working-class meal, it has recently undergone a popularity explosion; inexpensive places to enjoy it include the atmospheric stalls under the tracks at Shimbashi and Yurakuchō. Similar to yakitori are kushiage: skewers of meat, seafood and vegetables, coated in breadcrumbs and deep-fried.
If your tastes turn to pork, then you’ll not want to miss out on tonkatsu, larger cuts of meat also coated in breadcrumbs and usually served on shredded cabbage with a brown, semisweet sauce. This forms part of the king of comfort foods – katsu-karē, a breaded cutlet (usually pork) served with Japanese-style curry, sometimes served on a bed of rice. Lastly, there’s tempura, a series of battered, deep-fried comestibles including okra, shrimp (particularly tasty) and sweet potato; some restaurants serve a few varieties on a bed of rice (tendon).
How to eat in Tokyo on a budget
Tokyo isn’t exactly paradise for budget travellers, but as far as food goes there are some very good ways to stretch your yen. Most head straight to the city’s chain convenience stores such as 7-Eleven, AM/PM and Lawson, which sell snacks and meals round the clock; these include sandwiches and pastries, plus more intrinsically Japanese sustenance such as oden and onigiri (rice wrapped in lavered seaweed, with various fillings).
Not quite as numerous, but still found in all parts of town, supermarkets sell sandwich fodder and other staples such as bentō sets (rice with all manner of other ingredients, in a plastic tray) and super-cheap fresh noodles; note that in the hours before closing they tend to lop up to half of the price off sushi and other bentō.
If you want to eat out, try a standing noodle bar; these are usually referred to as a sobaya or udon-ya, though in practice the vast majority sell both; it can be tricky to operate the Japanese-only ticket machines. However, the best value is to be had at Tokyo’s fast-food chains, almost all of which supply English-language menus. All of the following can be found in every single part of town; just ask around.
