I have never seen so many unique items on a Japanese menu before. This place goes way beyond your typical California roll, although they have those too.
I had the opportunity to try hamachi collar, which was delightful.
This place is BYOB, so be sure to bring something to drink if you want it. Hana has all the glassware.
Bottom line - go here hungry, ask questions if you need to know what something is, and try at least one new thing. This is the place to do it!
