I went around 7:15 on a Saturday evening and they were extremely busy. So busy that it took about 35 minutes for us to get our order when we dined in. Luckily we ordered an appetizer to hold us over but we weren't expecting such a long wait. The staff seemed a little unbothered and weren't as friendly as I expected but maybe that's the NYC authenticity. Asking for a to go box seemed to be a big task for them. (Hence the 3/5 stars).
Food: Definitely order the garlic knots because they were heavenly. The pizza was really good--my favorite was the crust it had the perfect crunch. The slices are huge so be prepared to take leftovers. I didn't order the donuts because we were full but they looked really good so definitely going to try that next time!
All in all I would order the pizza again but I would probably call ahead and eat at home.
