T’s Tantan, an offshoot of Jiyugaoka eatery T’s Restaurant, boasts the distinction of having been one of the first places to sell proper vegan ramen in Tokyo. A feature inside Tokyo Station for well over a decade now, they specialise in Chinese-style dandanmen, served in a broth flavoured with sesame and peanut oil and available with a range of toppings.
There are three versions of the dandan noodles – the white, black or ‘gold’ (it comes with peanuts) sesame, all of which have a creamy enough finish to trick you into thinking there were animals involved in the process. If you’re calorie-conscious, know that konjac noodles can be substituted for the regular wheat noodles. On the other hand, you can add a side of vegetable gyoza or soy char siu if you're feeling particularly peckish, or opt for a non-noodle main in the form of a massaman curry with beans and mushrooms or a bowl of multigrain rice topped with the aforementioned gyoza and char siu, plus miso-flavoured soy meat and vegan cheese.
T’s Tantan can be found at the very end of the Keiyo Street shopping arcade on the way to the Keiyo line platform. Note that you’ll need to buy a platform ticket to get to the shop unless you’re already travelling on JR lines.
