Has anyone been to Billy's Downtown Diner? We are planning a stay in Bethlehem, for Chriskindlemarkt, in December, staying at the Hotel Bethlehem (in the "haunted" room), and wonder if the Diner is within walking distance? How is the food? I've read that it gets pretty crowded, which is a good sign! Are there any other good diner-type places to eat in the area?
