What I like most about BiBim Q is the service. The owners of the shop are ridiculously cute and friendly. They're always very polite and accommodating. This alone is worth going in.
Additionally, the food is good. Gamjatang is my favourite. It's done well here. It comes boiling to your table. The broth is slightly thicker than most soups and the pork bones are tender.
Overall, it's a great little restaurant that serves great gamjatang. Make sure you have a chat with the owners, they will make you smile for sure!
