I have been to the other locations before though it's been awhile (Green Valley Ranch and the Charleston and Decatur locations). Both of those locations have since closed. I was really hoping they would rebuild the one that burnt down on Charleston but last time I drove by another restaurant was being built. Don't know why they still have the address listed on their website if they are not rebuilding. Anyways, I absolutely loved going to OPH. This was the first time I had been to this location. You would think since they only have one location open in the area (Primm doesn't count) they would focus all their attention on it. We arrived and there was a 35 minute wait. Since it was 11am on a Saturday we expected a wait. We finally sat down and our waiter came to take our order. He came back with our drinks and we ordered our food. My son also asked for a glass of water. The place was packed so our waiter was extremely busy. He never brought my son's water and we couldn't seem to catch his attention. Finally when he brought our food we asked again for the water. The food was not cooked how we ordered it so that was disappointing. The waiter was bringing beverages to a table behind us so we managed to get his attention. We asked a 3rd time for my son's water and then asked for refills on our drinks. Finally he brought it out. We saw the manager but unlike other restaurants he never walked around to see how everyone was doing. He just walked between the kitchen and the register several times. Needless to say I don't think I will be coming back especially since it's not near where we live. Would much rather prefer to go to BabyStacks.
