Culvers has pretty good food and a good variety.
When you crave a greasy burger, this is the place to come. Seriously the burgers (and the patty melt which I love) are really buttery. The fries are good. Their onion rings are the BEST! There is no other place I've found that can beat Culver's onion rings. The custard is good--although not as good as some of the local joints. I do enjoy their concrete mixers and the shakes are really good.
The staff is generally nice, and the restaurant seems clean enough.
Its just a great place to come for burger and onion rings.
