I come here with my boyfriend a couple times a month. It's a decent price for an all you can eat Japanese and the menu is quite big. We don't really get any rolls and rarely get the sushi because rice fills you up very fast and their sushi has more rice than the average sushi. Like I said, the price is great and with the extra ten percent discount if you pay cash is even better.
There are extra dishes that are not put in the menu but are available if you talk to the owners. The owners are the oldest female waitress and the man that walks around with an apron.
Service wise is where they lose 2 stars on. The wait staff always seem moody or annoyed. If you order ten things you probably would only end up with seven. most surprisingly, even though the wait staff are young people, most of them don't speak English at all. The main language is mandarin and some Cantonese.
