I was told by my downtown working friends that this is a lovely place for pasta. Cheap and yummy and they were right. It really is a small cozy little place, so there is a bit of a wait and it may be hard to find seating inside (most people seem to order takeout).
We can the Carbonara and the Ravioli, both delicous but of they two, I like the carbonara better.
Basil Pasta Bar is at point p in the list "Places Part 1" on the map.
