Please don't go here. I went with a large group for dinner on Saturday. I love sushi, and I already knew I wasn't a fan of Sushi Rock, but they managed to lower my opinion even further. Absolute worst service I can imagine. We had at least 5 different servers (consecutively, not dividing the group to make it easier). Never took our drink orders. Had to ask at least 4 times to get a water refill. Forgot our appetizer completely, after we had placed/reminded the order with 4 different people. The rolls are like 3" in diameter so it's completely impossible to eat them like sushi is meant to be eaten, and they totally fall apart when you pick up a piece. Everything is swimming in mayo, even when we asked for it on the side. Disgusting. The bathrooms were filthy and broken.
On a positive note, they did take some things off our bill to compensate for forgetting them, and they were willing to accomodate our large and noisy group during prime weekend dinner time, which can't be said for all restaurants.
