I've gone here about five or six times in the past couple of months and I've had a pretty consistent experience. The servers generally do a good job but I've noticed that they are sometimes unattentive or take a while to fill up waters.
In terms of the food it has been pretty hit or miss but I would definitely recommend to stick to their "favourites" items like the works burger or the soft tacos. Those are the items with the little lightning bolt, get one of those and you wont be dosappointed.
Also if you get the fries a heads up that they have an insane amount of pepper so caveat emptor.
Feel free to shoot me a message before going and I cam give you a recommendation on plenty of the menu items as between myself and my friends I've tried nearly all of them
Also be wary of the conditions inside it gets really hot and really loud so you may want to request sitting outside.
