Yes the service may be a little gruff. Yeah, the ambiance may leave a little something to be desired, but this place is DELICIOUS.
The kalbi and hot pot are my go to winter favourites. Warming, flavourful, fresh and filling. It's really good value (three-four very hungry people can eat well for $20 each.) And I kind of enjoy the charm of it taking several reminders to get your diet coke.
