There are a few "Theories" or general rules of thumb that seem to hold true. Sam Sifton came up with The Pizza Cognition Theory (basically the first pizza that you appreciate become what pizza is to you, might be Dominoes, or local place you went to aster a game, that's what you look for in a pizza). Angelo Womack has a theory about the quality of a pizza being directly related to how formally dressed like a chef the pizza maker is. If you look like you were just chef-ing it up in a super formal fancy restaurant, the pizza probably isn't very good.
Here's my Pizza Line of Sight Theory:
If you are in a pizzeria and you cannot see anyone making pizzas, the pizzas is not going to be great.
Sure that pizza might be passable and fill you up if you are hungry, but those slices are never going to be in the discussion about great pizza. I tried a family dinner package from a local place I had never tried out before tonight. I had driven past it for years but the last time I looked it up online the photos were of pizza I was pretty sure I was going to hate. When I looked tonight, the pizzas looked like they could be OK. So I got the large cheese, boneless Buffalo wing bites and garlic knots combo, Picking up the order, there was a display case with slices. They looked OK. I was getting my hopes up, even though all things pizza production were in a back room kitchen.
Opened the box and looked at the bottom of a slice. It was cooked on a screen. Another theory: Great pizza is not cooked on a screen. Again, pizza on a screen might not suck, but I don't know of a great one. Tasted it, the crust was bland. The texture was commercial. I'd bet this place is buying dough instead of making it. The boneless wings were clearly premade/purchased. Overall, the pizza looked like it might be alright, but it wasn't.
Anyhow, let me know if you have a place that disproves my line of sight theory. In my experience, it has been rock solid.
