As far as the food, it's DQ, same as all the others. The reason it is rated terrible is because of the service or lack of it. It can take up to a 1/2 hr just to get an order through the drive thru, inside is as slow at times.
We don't have a dairy queen where we live so it was a novelty for our children. Wife and I went out to the Snaffle bit and the kids ate burgers and shakes and just chilled by the pool. They said they liked it.
I have two very picky young children, and this place made everyone happy. The prices are very reasonable and the food was typical DQ fare- burgers, fries, shakes, chicken strips, and lots of ice cream choices.
