I love this place! I used to go to the original Markham location to have their buldak (blazing spicy chicken?) and yang nyum chicken (sweet and spicy chicken?). It's an old favourite and whenever I crave some good old Korean chicken, I go there. I've only had buldak at the Bloor location and it's still pretty good, although I find it little less spicy.
At 710 Yonge St, my favourite is the fried chicken. The salt/pepper that comes with the wings is like crack! I sometimes just taste the s+p alone... it's that good. I've also had the lunch menu: the tofu soup, pork bone soup, and the rest are pretty tasty and very affordable for downtown.
The decor is not that fancy, but it's very typical in Korean restaurants (let's be honest, we go for the reasonably priced, delicious Korean food). The service is pretty good too: it doesn't get too busy during lunch hour and is only serviced by one waiter usually. Anyway, I'll keep coming by!
