Sushi Rock wasn't as bad as I thought it would be based on these reviews, but it definitely didn't blow my mind either. It's not the best or freshest sushi I've had in Cleveland, but I would be okay eating here again (only for half-price sushi though.. I'd probably never pay full-price here). We tried one of the large rolls which was my favorite part, and the nigiri was definitely the most disappointing - probably because it was more obviously not fresh tasting.
Our server seemed a little inexperienced but was nice and attentive. The restaurant didn't feel dirty, but it didn't feel warm and clean to me for some reason. Overall, I'd come here again if someone else wanted to, but I think that there are definitely other places where you can get better sushi for the same price.
