Atami is very similar to many other japanese express restaurants, but in a good way: they always give you tons of food, and the shrimp sauce is excellent.
I've been to some sub-standard japanese places before, and compared to those, Atami is cleaner, bigger and less greasy. The sweet tea isn't very good though. What's up with Chinese and Japanese restaurants serving sub-standard tea?
Aside from that, Atami is a great place to get a quick, good tasting meal. The service is prompt, and the bill at the end of the meal is small. When you're looking for a quick lunch or dinner, what more could you ask for?
My pick: Hibachi chicken with mixed vegetables. Don't forget the shrimp sauce. Yum.
