The staff is certainly friendly, but after five visits this year it's apparent that they aren't very well organized. Each visit was different but off-kilter. One waitperson asked us if everything was alright every 3-4 minutes, they messed up some orders, once we had our food 2 minutes before we had silverware, etc.
The food is predictably good but the service is predictably unpredictable.
This is a wonderful restaurant. I live in Marietta and I will give you a tip. You get better food and service on the breakfast lunch shift. You see the dinner shift is mostly younger people and dosen't seem to care as much.
