I ate there for lunch yesterday. It was darn good. I usually don't like steak houses (Ruth's Chris, Morton's, the Palm, Sam & Harry's), but CP's was definitely better than any other steak houses I've eaten at.
They weren't perfect, though. The guy I ate with got the "porcini crusted halibut" which didn't have even the slightest detection of porcinis (or even crust) on it. The fish was just pan fried in butter. It looked like they forgot to encrust it at all. When brought up to the waitress, she was kind of snotty about it, but eventually stuffed it and became quite accomodating.
