Underwhelming. My fiancee and I had a couple of friends in town, and they love OHP so we went. I had never been before and was anticipating a cross of IHOP and a cool brunch spot. Turned out to be an overhyped Waffle House in my opinion. We waited about 30 minutes to be seated, then ordered drinks. Our server, Jessica I believe, was great. She was very attentive and timely, always checking to make sure we were ok and didn't need anything.
I ordered a bacon egg and cheese sandwich with a side of hash browns. Not especially terrible, just extremely bland. The hash browns tasted like cardboard, so they were subsequently drowned in ketchup. The sandwich wasn't bad, but again the eggs lacked much flavor.
For the price I guess I can't complain too much, but I would rather spend an extra $5-$10 and have my socks blown off at a brunch spot somewhere.
