The Palm is a pretty standard steak house, part of a chain. Noisy and boisterous. if you like this sort of thing, you might enjoy it.
The Sunset Grill is the main restaurant. Very good at breakfast and lunch, with the menu changing to more "serious" contemporary cuisine at dinner, which might not be to everyone's taste.
The closest HRH gets to fast food is the Beach Club, which serves sandwiches and burgers.
I've never tried getting anything to go, but you can always use room service.
