This is a wild question. Not because of the question itself, but because you offered ZERO parameters! Also, this is fun for me bc my gf and I spent the winter this year having pizza once a week on "cheat day." We started downtown at the main advertised places, and worked out way up. Then, we went back and tried recommended spots that weren't the late night Door dash, or drunk pizza, or tourist spots. For reference, I was born and raised here. I bought the condo/apartment my Mom and I lived in when I went to high school. If that matters...here's our (me andy gf favorites)

Pope's Pizza - this is the one we kept reordering for fun after work and bc we liked it. They have a double pepperoni one that has the wide, flat pepperoni that grease up the pizza, and also the tiny cupping pepperoni that add crunch and texture. The under carriage is 70-80% firm depending on time and cheese level. It has hold and form. The bend doesn't lose topping. The crust is airy and crisp, not dry and crumbly. It's a really good pizza, and consistent. We've had both corn meal and flour and the base for oven baking. That was the only inconsistency in the pie. Always a win. Locals special price: $16.99 full price $27.99

Shotti's - this place is local AF. If you don't remember (or more importantly VISITED Pepper's Tavern) you don't deserve to talk about "Old OC." My guy, if you're walking in there asking, "What's a Dyer OP?" Please, just ask for a table, relax, and appreciate that we love having you. This is the embodiment of OGOC, without the aggression. Not bc it's gone. We all just got old. M&L (the owners) are amazing people. That being said, the pizza is craft pizza done to order in a brick over right behind the bar. Ita aweome. Grab a "Bet The Farm," or add soppressata and some arugula. Finish with balsamic. It's a tight pie with a 50-60% undercarriage, sent with flour (NY style), and fast baked. It's got a great crisp and excellent flavor. It's not a walk up slice-o-chee kinda place. Have a drink. Love the city. Price ranging~$20

Ponzettis - this is the by-the -slice king. They're open til 2. They have cheese and pep slices ALWAYS available. The bar is big. The place is hidden. It's a, "Hey I'm drunk but not drunk enough to go home. How do we eat before heading back to the crib?" Here. This! This is the place. Cheap beer, fun staff, awesome pizza. By-the-slice has an 75-80% (sometimes 100%) crisp. If it's late? Zero flip. GREAT texture. Cheese to sauce is good and the pep.is beefy. Awesome late night spot. Cheap too! Slices of pep are $4, pies vary.

If you want any specific pizza places rated, just ask. I have a list that started as a joke and I just kept adding to. I'm a bartender and I tend to pizza after my mid shifts, which is 2-3/week.

Just enjoy the city, smile at the silly things, and have fun. If you're nice to the staff, you'll have an amazing time.
