I too wish I could give a 3 1/2 star rating, three is a bit low, but it's not worthy of a four.
This is one of those places that you certainly must go for the experience of it. We went to celebrate a friend's birthday, and upon arriving we were greeted by friendly and knowledgable staff, and as this was our first time there, they gave us the "lo-down" on ordering in "sign".
There were picture instructions on the menu to help us order, and the waiter was friendly and very helpful, and he would help coach us on our food order if we weren't able figure out the signs.
The decor was bright and contemporary, green seems to be a favorite color theme.
The food was flavorful, however, we found it quite pricey for the portion size. The drinks were priced on the high side as well and they also already add a 15% gratuity right in your bill, so pay attention you don't "double-tip".
You'll I enjoy the experience of learning sign, but I think if you want more bang for the buck, somewhere a little less trendy would be better.
