Py, the new brick-oven pizza shop on O'Donnell Square, is so narrow that customers can almost stretch out their arms and touch both sides at the same time. Seating is limited to six wooden stools -- two that circle a small table, and four that cozy up to a shelf just wide enough to hold a paper plate with a slice of the shop's excellent pizza.
But customers don't seem to mind the lack of seating, especially in the wee hours of Saturday and Sunday mornings, when they tumble out of the bars on the square and stand in long lines for pizzas and calzones, which they eat standing up or take with them.
