Here in Washington DC, the best pizza place in town (2 Amys) uses a Woodstone Oven. They keep the temp at about 625, I believe (based upon the temperature read-out on the side of the oven). I know this temp is low for true Neopolitan Pizza. I would say that they do have fabulous pizza which seems fairly true to the Neopolitan style (until I get to Naples or to spend time with PizzaNapoletana, I guess I cannot say this with any certaintly.)
I do note that I have been in other places with Woodstone Ovens that are just horrible, and the oven seems to be more "show" than "substance".
