I was thoroughly impressed by Kiyomizu because there are numerous Japanese restaurants around the area. This restaurant is run by Koreans but are extremely friendly and attentive in regards to service.
They offer lunch specials until 3pm and an extensive menu. The price is average, a little higher for some but I felt it was worth the quality of sushi I received. I got the spicy salmon rolls and lunch bento (chicken katsu) with salad and two sides (deep fried japchae roll and salmon). I forgot the prices but I think this is my favorite for spicy salmon rolls.
My friend and I also got complementary calamari. Overall I would definitely come back and try the other items on the menu. Worth checking out again! :)
