Ganadara always has such a long line that Kantapia might be a good substitute. Bustling place, and we were 5th in line but we were in and out in about an hour due to the speedy service.
Large portions for appetizers, and I liked that the free side dishes included more than just kimchi.
Only complaint is that the bibimbap (stone bowl) was not prepped to a high enough temperature. It wasn't hot enough to turn the rice into crispy pieces and sizzled for less than 5 seconds I would guesstimate. Should be much hotter!
