Looks like I'll have no problem finding good eats in York, thanks guys. We've got a Five Guys and a Mission BBQ here and I enjoy them both. We often try to be at the Mission BBQ at noon to participate in the National Anthem, always Outstanding.
Would be very interested in "York only" restaurants or Pennsylvania favorites, as the Cheesesteak and Lager sound great. I may try The First Post Public House, White Rose Bar & Grill, and/or Iron Horse York as @rplst8 suggested for a bit of local.
