Yasu is not at all what you would expect by looking at it from the outside. It is a rather small restaurant, but that adds to the ambiance. We went on a Saturday night and it was pretty full. Customers ranged from families to couples out on date night. We were greeted immediately and the service was excellent. The server explained everything on the menu (there are a few different menu's) and offered his advice after asking what we were looking for to eat. The drinks were good and the food was fresh. The menu offers items you don't typically find at other sushi restaurants in the valley. The boneless ribs on the 5.00 menu were excellent as was the seafood fondue. The prices do get a little expensive with some items, so it is worth checking out during the times where they are running the food specials if you are really hungry. Overall a really nice and unexpected experience. We will be back again to eat there soon!
