I think it will fill a niche fairly well; I've had their pizza in South Station and liked it. (Certainly moreso than the last time I had Mike's.) The pizzas are relatively small and fast and expensive, though; I think they'll fill the "hey I need some food before this movie" niche well, but not so much the "let's get a pizza for dinner" niche. Also they're thin and crispy and get cold fast, so benefit from immediate consumption vs. takeout-for-later.
