Do you have to make reservations for the big party looking area or can you just go in and sit there?

I would recommend reservations. It gets pretty busy!

Best to make a reservation. It was a really fun night there

I would also suggest reservations, one of my favorite pizza places, although, I know & have heard ppl talk about many of their other items, I can't seem to move past the pizza, smiley face. Have fun!

It's better to make the reservation so that you know you have the whole area needed for your group size. They have a couple rooms they will close of the one that will fit your group if you arrange ahead of time

Both

I think you can do both. Take a risk just walking in though.
