I LOVE Johns! If you are going to be a tourist and eat at a place in Times sq, this is a great option. I have been there on many occasions, and it the food is pretty good! It is also one of the best places to bring a group as it is quite large and you can usually get in.
John's is a great Pizza option in midtown and they take large groups too. This used to be the chapel for The Covenant House. This was the place where runaways were able to live here (many outreach programs)during the 70's and 80's (I believe). It was on the nasty stretch of 8th avenue nothing like it is today. I was in the chapel a couple of times while it belonged to Covenant House because my friend worked there(small chapel not like the writer said). I guess that means it was something else (bigger church) prior to Covenant House purchasing it.
I question their claim that they are the largest pizzeria, but it is a great place.
If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
