Their mild and sweet fried chicken is legit. The sauce is *exactly* the same as that used for the 'yangnyeom tongdak' you'd eat in Korea.
I think the secret is in the heavy taste of garlic and also the chopped peanuts. It's a classic that's hard to replicate one hundred percent, even for many fried chicken restaurants in Seoul these days.
So if you're eating Korean-style fried chicken at any other restaurant in CU, you're basically wasting your money.
Can't comment on anything else because I normally order to-go.
