I may be in the minority here but I hated 50's PTC. I will never be going back. The food was greasy and terrible. The only thing that was good about that place (and i know this is me being a guy) but it was the waitress. She was rather pretty but other than that, nothing.
I haven't eaten at Beaches and Cream but I have had the ice cream there. Long lines and a bit overpriced but the ice cream was real good. I would go here or even find another place.
