GOGI is a welcome addition to the (few) Korean food options in the Phoenix area. The soon tofu soup is pretty good. Would be nice if you were able to increase or decrease the spice level for varying tastes. I felt like something small was missing, though I can't quite put my finger on it (maybe more anchovy)? Still tasty, however. We also had the bulgogi and pork bulgogi, both of which were excellent. Like other Yelpers have mentioned, the banchan (sides) were also great!
The service here is wonderful. Very attentive and quick to refill your drinks and side dishes.
Price is reasonable. As expected, the lunch prices are slightly lower than dinner.
Would go back!
