I love the food at PTC. I've never tried WC but have heard mixed reviews on the food. I think the experience at both places can probably be really good if you get a good server.
That doesn't really help does it? If it was me I would look at the menus and see what the people in my party might like. I would also want it to be different from other dining that I was doing on the trip.
Either way I'm sure you will have a great time!
