Although I've never eaten in the main dining room, I usually come here for some good Italian food for a quick lunch. Their pastas are pretty hearty and tasty, as are their scaccias. There's a decent selection of sandwiches and cold pasta salads as well, in addition to some cakes and other dessert items.
Although I do like their food, service is a bit subpar, with indifferent and unfriendly staff behind the counter. There's not much that really makes this place stand out, but if you're in the area looking for a quick reasonably-priced lunch, then Scaccia is a good option.
