Sushi Hama is... OK all things considered. I have always come for the AYCE dinner and the selection is pretty basic. The quality is fair and they provide a lot of options for people that do not like raw items. You can get things that kids or non-fish lovers would eat, like the noodles, beef, and eggs. They also have ice cream to finish off your meal.
They have a small selection of sashimi - tuna, salmon, mackerel and beef cover most of that part of the menu. The sushi options are pretty typical, including hand roles and some unique ones to Sushi Hama. But there are no baked roles or anything that sets it apart from other places I have been to.
The bad part is that service can be really slow, and have waited extended periods of time when its not even busy. The restaurant has a couple different levels and its hard for the waiters to tend to everyone efficiently.
