Very large portions and very poor service. The place is clean, but no one was there! Usually not a good sign. The waitress didn't deliver my food as my group received theirs, and had the nerve to ask me what I ordered 20 minutes after I had placed my order. I then waited another 15 to get my food. No one in our party received plates for our appetizers. The sushi looked fine. The portions were very large for the price. Seems like a nice place for a group lunch. You can probably find nicer places for dinner. A date may work here if you are a cheap punk with no style.
The food is average with awful service. Not a good combination. Mill Ave. is a tough crowd to satisfy, but this place will thrive because location, location, location...so I wonder why Pizzeria Uno's disappeared (it was in the same location before it closed)? Don't expect this place to be around for long with its standards for service.
The little things and the big things matter, and Kanpai misses on both accounts.
