Overall I'm a fan of of Bibim Q. It's authentic, tasty and they offer a good selection of Korean foods. I will echo that the service is very friendly, and that the staff is very polite. The white gentleman behind the counter is actually the co-owner with his korean wife. They are a sweet couple who really make their customers feel welcome.
The layout and decor is basic, but it is not designed to impress. The place is about good, affordable everyday Korean food. Koreans I know enjoy the restaurant, and they play contemporary Korean music & K-Pop which I enjoy.
It's my favourite place outside of Korea Town for Korean, but beware the small seating capacity. As well, during winter the tiny space can get mighty drafty with the door opening and closing, but ignore it and enjoy the food!
