Maybe it's just because I'm a sucker for fried chicken, but I love this place. The first time or two I went I got a half chicken (first sassy, then bbq) and it was good, but the wings are the way to go (the chicken pieces dried out too much for me). The wings are very large, fried hard (which I like and with wings that large they still have juicy insides even with a good crunchy fry job), and I think that the bbq sauce is awesome. Authentic? Probably not (I can't say I'd know as I'd never had Korean fried chicken before this place) but man is it tasty.
Maybe there are places in town or out in the burbs that do a better job, but being a 5-block walk from my house, I can get a pot of water going, call in my order, take the dog for his walk, grab the wings on the way, blanch some veggies when I get home, and be a very happy camper for the evening.
