This place is awesome!
They're very friendly and polite, they recognized us the second time we went (and every time since). The All-You-Can-Eat is a great deal, it even throws in some extras like saki shooters. The half-orders on rolls is a great option. There's non-fishy options for those dragged along for the sushi experience. They even offer a frequent-eater punch card! (Buy 10, get 1 free?)
The ONLY bad thing about this place? It's hard to find! The map shows it completely wrong! It's the SE corner of Centennial and Simmons.
