I've only been there once, but I felt like there was one really good pizza (the one with Bari sausage) and a couple of others that I didn't like nearly so well, though even so they were obviously better than at least 70% of the generi-pizza sold by the slice around town. I need to go again, although it's hard for me to do so because I end up passing half the woodfired pizzas in town on my way.
My main impression from the white, New Haven-style pizza was, oh good, now we have one, so people can stop asking where to get one. But I'm not sure I need to try it ever again, or at least again this decade. (But then, I wasn't walking around thinking Chicago pizza was broken before Spacca Napoli opened, either. I thought it was in pretty damn good shape, frankly...)
Anyway, I lean a little toward the premature side, also. Or maybe it's not premature any more, but I haven't been, so I don't know. Has the menu evolved? Has its pizza hand developed? Has its promise been fully realized?
