I eat here fairly often. I like the sushi (a lot more than the Kona next door. At kona, it's always super fishy). This place is a modern, hip environment. The servers aren't super nice - they give you basic service and just leave you alone. Which some people like and some people don't. I personally like it, as long as my food is hot & out in a decent amount of time & my drink is full.. I'm happy. I don't need small talk from a waitress.
The Martinis are good but expensive. Happy Hour is the best time to visit - but the staff moves slow on purpose to limit the stuff you can get.
Overall I like this place - but it's for a certain type of customer. Get the crab wontons, and the mango wango.
