I thought this place was pretty OK - probably their biggest selling point is that they're open very late. It definitely looks like a place that's open late - tiny, cramped, and kind of grungy.
The pizza is pretty good, and they've got a good selection of toppings/varieties, even into the wee hours of the night. Like Pizzaiolo, you get the large double slice for $4, and they heat it up in the oven for you. If they get crowded (which actually happens sometimes at night) then you have to make sure to insist they put it back - their pizza is pretty good when it's hot, but it's downright nasty when you have to eat it cold.
