Try one of their Japanese parfaits made from traditional ingredients and matcha soft serve ice cream. As you might expect, the decor is pretty Zen. The name of the place literally means "temple cafe". It's decorated with multi-coloured Buddhist flags in front of the window so you shouldn't have any problem to spot it.
Nataraj ナタラジ (Ginza)
For Indian vegetarian cuisine, this is the place of choice for many connoisseurs. There are so many good Indian restaurants in Tokyo, and this one is one of the best! There are so many types of dishes to choose from. The curry is, of course, excellent and is dangerously addictive when you eat it with the freshly baked naan bread. What is most awesome is that they have an all-you-can-eat lunch buffet that is only ¥1,130 (90 minutes) which includes 4 types of curry and many salads and side dishes. The cuisine is southern Indian, but it isn't too spicy. A must-try regardless if you are vegetarian or not.
Located a 5-minute walk from the JR Ginza station.
