Caffe Buon Gusto [236 East 77th Street, New York; Menu]
Small and cozy, this is a very tasty choice for dinner. You can create your own pasta or choose a specialty pasta such as the black linguini with calamari or the green and white linguine with salmon that I had. Prices are affordable and of course other Italian specialties are available as well. I recommend reservations on weekends, as it is a pretty popular place.
