I'm guessing the four star rating is because this is a great place to go for a drink in between making batches of meth.
For anything else I don't see the appeal. There was one bartender/server and one person in the kitchen on Saturday afternoon and it took two hours to get any food. The bartender/server was slurring her words and took orders three different times and still didn't get it right.
Food was ok but not anything special or fresh and not worth the wait. There was "something wrong" with the Blue Moon keg.
While you are waiting you get to experience the wonderful clientele and have your clothes absorb the ash tray smell of the inside.
At least it's cheap and if you are lucky at the slot machines inside you can pay for your food/drinks.
