It is an interesting choice of both the Korean food and the sushi. I will first say that they have a pretty exhaustive sushi selection with many specialties. I tried the ultimate tuna and was mildly impressed. It had the tuna meat on the outside, rice in the middle layer, and a spicy sauce and tuna mix in the middle. I also had the Korean-style chicken and veggie stir fry. It was okay but I think the other Korean restaurants make it better. The spiciness was just right though. The waiter service was prompt and we needed to go up to the register to pay. I would think both Sushi Rock and Sushi Avenue are comparable but Sushi Rock is closer to campus. Whether it is worth the extra walk is up to you. I would prefer Sushi Rock because I prefer the Japanese food over Korean food with my sushi.
