Yesterday after a wonderful visit to the zoo -- baby elephant, amazing pandas, baby gorilla, etc. -- we stumbled into Vace Italian Delicatessen at 3315 Connecticut Ave in Cleveland Park. I had vaguely heard of it but living in Va. don't get to this part of DC too much.
Anyway, the pizza is good and cheap to boot. We tried a slice of the onion (a white pizza) and a slice of mushroom. It's almost an elegant pizza; pretty thin crust, sparse sauce and cheese. Nice tangy sauce on the mushroom slice, while the onion white pizza had a lot of onions and a nice amount of oil and garlic. Not what you'd call NY style pizza (far too thin and lacking in cheese for that), but for this area, it jumps to near the top of our list.
