This restaurant has done an amazing job of upscaling the Korean BBQ restaurant to what one might see in Seoul. Not only that but it has maintained an amazing reputation, good quality, pretty good service, and a nice price to complete the package. Many of the non-Korean people I know have experienced this restaurant and I am proud to say it has become a bit of a hallmark for Korean BBQ in Calgary.
I would encourage going with a Korean friend as the service usually gets better, and they have a better idea of what to order. The BBQ combos here offer a great variety of meat and side dishes and the price tag is honestly nothing compared to the amount of food you get.
It's definitely become very popular and busy so the service isn't always spectacular (did you know on the weekends this restaurant only hires men because of the strenuous work load?) but if you don't mind taking the time to cook your own meat (and don't order much of the side dishes) then your dining experience won't be totally ruined. Also for those of you who complain about the service, in Korean restaurants servers don't come to the table unless they are called (it's a cultural difference! not that they don't care). Again my advice about taking a Korean friend will help you here!
PS. If you haven't noticed I am Korean and I'd love to be your Korean friend =) How can I refuse a free meal at Korean BBQ?
