Just came back from American Flatbread in Arlington. They are serving until 9pm tonight, and they offered me everything at half price. So a $15 pizza came out to $7.50. Can't argue with the price.
Or the pizza.
I had a "Revolution" pizza with caramelized onions and mushrooms. I couldn't stop eating it. The onions add some sweetness, so just get the plain pizza if that is not your cuppa.
You should make a reservation if you want to get in tonight. 703-243-9465. On the corner of 11th and N. Fillmore.
