Finally went to Gonpachi....Very impressed. The courtyard has an ancient wooden gate, koi pond, and Japanese garden. They've really put a lot into the details of the even the rain gutters. When you go inside, the main dining area is like a Japanese temple.
The food: They make their own saba noodles and the sushi is delicious.
The waiter: The sake waiter, not the food waiter, comes to take your sake order. He's from Japan and knows everything about sake.
Highly recommend this restaurant. 4 stars out of 5
