This is my favorite Korean restaurant in the west valley. I'm a long term valley resident, and have been a fan of CGJ Korean BBQ and Pho Avina since their beginnings at the shopping center across from ASU West.
I've tried the other Korean restaurants on the west side (Takamatsu, Seoul Korean Grill) and don't think they compare. I love the tofu soups, the bibimbap, and side dishes (my favorites are the lotus root--when they have them, and the sweet potato salad). I also like the fact that this is a small, intimate family run establishment as I prefer mom & pop restaurants to generic chains.
I would recommend getting a normal menu entree as opposed to the lunch specials on your first visit. The lunch specials are priced cheap for a reason, and don't give you a good idea of the quality & flavor of real Korean food, plus you don't get the delicious side dishes.
