Regular at this location of St. Louis (since I'm local) and it's extremely on-off. One day you can come in and get stellar service from the waitress/bartender and quick food, and the next you can get super-lousy wait times. missed drink orders, and sub-par food.
Tuesday nights and any major sports game-night/UFC night will always be crowded, so come early if you want a seat and decent service. Their service during busy times is extremely poor - they need to pick up the slack in order not to get so many negative reviews.
The chicken is usually cooked fine (I always get Cajun), I've only had one incident out of 2 years dining there where it was undercooked. The fries are varied - they can either be fresh and delicious or cold and soggy (if you want better-quality fries, go on Thursday and order a half-price Poutine). The sweet potato fries are amazing - they make them to order versus their regular fries and are always guaranteed delicious. The ribs there are inconsistent as well, but their burgers and salads are alright.
Overall: consistency is not great and service can fall off quite hard, but for a solid wings + fries experience this is a decent choice.
