Lupa is one of my go-to places in the neighborhood. Not too long ago, they extended their hours so they are open straight through from lunch to dinner. If you go after the lunch rush and before dinner you can walk in with no problem. The menu is pretty diverse so you can have a snack or a full meal. We had the Frutti de Mare--Cod, tuna, striped bass, sardines, clams and calamari.
