Quick response needed re: Williamsport eats
I highly recommend the Bullfrog. It's a brew-pub with great food. I highly recommend getting their beer sampler and the fish and chips.
Le Jeune Chef at Penn College campus is excellent, as well. It's run by the students in the culinary program, but it's probably the best food in the area. Very reasonable prices, but the service is usually a little lacking. Go for the Chocolate Soup as a dessert. It's really amazing and unique!
