A couple of years ago zpizza moved into the DC area, and quickly became our favorite for neighborhood chain pizza. Not too doughy and relatively generous with toppings. Naturally, our franchisee soon turned his locations into the inferior Manhattan Pizza (not quite as bad as Domino's or Pizza Hut, but still not great).
I now see that there are still several zpizza locations in Northern VA, including one in Gainesville.
Not that I would drive out of my way for zpizza, but I'd like to have their Tuscan again. It's got very nice mushroom flavor.
