I have been going to Vace (the original in DC) since I was a child. The Bethesda outpost has the same fare. Inexpensive traditional pizza by the slice as well as good Italian deli sandwiches. The counter is efficient making it a nice place to grab something when in a rush (although parking in the front can be a bit of a trick). Pepperoni pizza, white pizza with spinach, spinach pie, and subs are all good. There is also a nice selection of pastas, olive oils and other Italian imports.
