A few years ago, I used to frequent this place pretty often. Recently I have found that the quality isn't as good anymore. The last time we went, we couldn't stop drinking water during and after our meal. This was a clear indicator, that we were consuming a lot of MSG.
Lots of choices for rolls, but it's a pretty standard AYCE. Service is quick, but sometimes food items are overlooked. My favourite is the firehouse roll, which is shrimp tempura and banana on the inside, topped with tuna on the outside.
If you're going as a big group, consider making a reservation.
