Korea Garden's BBQ is 191873904172x better than Sushi Kim's BBQ. Since Sushi Kim's bulgogi is sosososo bad, that really isn't saying much. Korea Garden's bulgogi actually has flavoring, sauce, and is NOT like eating rubber paper.
The number of side dishes at Korean Garden is not as plentiful as other Korean restaurants that I have been to. I cannot complain about that shortcoming because in Pittsburgh, the sample size of Korean Food is '2' . The beef short rib is a little thick.
I have only taken the food to-go, so I cannot comment on the service. The hostess who takes my order has always been very courteous, cute, and nice. Make sure you park legally, as I have seen several tow trucks in the area.
