I first heard about Chili King via Seoul Eats and was curious to try it, particularly the chili burgers. So I recruited K. again, and along with M., the three of us checked it out for dinner this past Thursday.
Instead of a chili burger, I ended up ordering a bowl of chili, K. got a bacon cheeseburger and M. ordered a chili dog. The chili itself was a solid, meat-and-beans chili, evenly textured and spiced (I'd say on the low end of medium-spicy for me) topped with a bit of cheese and accompanied by sliced French bread. M. really enjoyed his chili dog accompanied by crinkly fries, and K. liked her burger (well, it had bacon on it, so it had that going for it at least).
The waitstaff were friendly and seemed to speak English pretty well. Unlike Butterfingers, Chili King is located relatively close to me (in Itaewon) and I could see going back there again, though it's a bit spendy for a bowl of chili (8,500 won). I don't know if I'd go back just for the chili, but I could see getting a chili dog again.
