This place is a hit of miss. The burgers are tasty [the food truck versions are better] but the service can be awful.
I've had the range from pleasant and efficient to catching them bad-mouthing my group who had left them a good sized food and an even bigger drink bill [during happy hour non-the-less] and still had the audacity to loudly complain we made them work while we were sitting 2 seats away from them at the bar next door.
Take it what it is. Consistent and decent enough quality.
