Mystic Pizza, made popular by the 80's movie of the same name fearturing a then unknown Julia Roberts, is a definite stop when in the area. The walls are adorned with photos and posters from the filming of the movie, which is good because you will find yourself looking at them during your (sometimes) hour wait for a table. Unfortunatly they do not take reservations, so try not to come during the lunch and dinner rush or go late at night.
The menu features plenty of pizza choices, subs, Italian dinners and seafood. My personal favorite is the meatball and onion pizza. A medium thick crust topped with melted cheese, sliced meatballs and lots of thinly cut onions.
The prices are on average for a pizza place, and can be a good deal for a family depending on what you order.
