You can't say you offer New York style pizza or are similar to New York pizza places if you run out of slices and don't make more. IIt's not difficult. Otherwise it's not bad, though their pepperoni does not look/taste like pepperoni, more like salami.
Update: there's no reason someone should have to wait 10+ minutes to pick up an order that's already ready for pickup, when there are 4 employees working. I'm not unsympathetic if it's busy, but it wasn't.
