Tokyo Vegetarian Restaurants: No 1 Pick is T’s Tan Tan, Tokyo Station.

You’ll find T’s Tan Tan inside the JR station, at one end of a passageway called Keiyo Street which is marked on the Tokyo station map inside the station. It is well worth tracking down! Really friendly, clean and airy modern restaurant. Up to a dozen ramen or tantan vegan noodle dishes, and sides like soy meat or dumplings. We loved it and went twice! Deserves its #1 ranking. Ramen and side cost about 1100 yen.
