There's an all you can eat sushi buffet near me. It's meh.
I like sashimi though. When I do go some place decent, I almost always end up getting chirashi. I think my top four things are the white tuna, mackrel, octopus, and spicy scallop rolls....super spicy scallops.
There's a place called House of Kobe in the next town over. They had a really good sushi chef, that I got to know, that made it worth going. He would fix us all kinds of strange stuff and was just a really cool person. Too bad he left though...
One friend went with me that didn't like seafood at the time (she loves sushi now) who was mortified at eating raw fish. He fixed he a ham and cheese roll and she was tickled. One day he made us seared rare beef nigiri which was awesome. He also made a Japanese energy drink. It was quail egg, blue caracao, and sake.
Thanks to him I've tried a lot of different things I don't think I ever would have if left on my own.
