I really don't get all of the hype about Sushi Rock. Yes, it has a fun atmosphere and the sushi is decent, but I don't understand why every in Cleveland goes crazy over it. The sushi is average, however the Cherry Infused Martini is amazing. I never go on half price night because unless you make a reservation, you have to hope that you can get a bar seat. And if you go on half price night, plan on waiting for your food forever.
It is a little expensive for what you get. I have been to better places in much larger and expensive cities that were less expensive but MUCH better. Sushi Rock is okay from time to time, but I wouldn't say it is a must have for a Sushi craving.
