Live in Clarendon, and have tried it twice now. The pizza is unimpressive. I get that it's "new haven" style, but it's a lousy rendition. The service is unreliable, and the pizza is not memorable. It leaves much to be desired.
For an amazing pizza, try the Italian Store (within walking distance) where Sandra Bullock visits when she's visiting her hometown (Arlington)! There pizza is to DIE for!
