I've been going to this place for about 3 years now, and I haven't been since last August, until last night. They've added a few new items to their menu, and overall quality has improved. Don't expect the best but I enjoyed every roll I ate last night. The bbq in the middle of the table is fun, and adds to the experience. Sometimes you don't get all the sushi you order, but hey, who doesn't over order at all you can eat anyway. Our server was also great.
It's good for an all you can eat place. Price wise, it's probably the same as going to your favourite sushi place and ordering quite a bit. I still go because I like the bbq aspect, and I can order all the yam tempura and gyoza I want :)
