A bit outside of the heart of Roppongi, half way to Azabu Juban or the Grand Hyatt, lies this small wooden house stuck between 2 buildings and opposite a Konbini. you could walk past without realising. Ganchan has 20 seats, a counter and one table. 4 men run the place and they serve til late which is unusual in Tokyo (even in Roppongi).
I always take the Japanese course-meal, it is a set menu with 10 yakitori that they grill on a small stove in front of you, very tasty, you get appetizer, oyakodon and a dessert as well.
Best to book, I like it!
