I'm in the camp of "you can't do pizza wrong".
Here are a few of the pizza places we frequent:
In Minnesota:
Papa John's - when we are in a hurry and just need a couple of pies delivered or carry out.
Papa Murphy's - take and bake has its place, usually their stuffed pizza for the adults
Frankies - a decent Chicago style pie
Jet's - Love their 4 corner and 8 corner Detroit style products - always carry out
Sammy Perrella's - Family recipe cracker thin crust - always in restaurant with a side salad
Green Mill - Chicago and Tavern styles - in restaurant or at the State Fair
Punch - Wood fired oven Italian style (Margherita and Neapolitan)
In Ames:
Happy Joe's - RIP - Taco, Taco Supreme, Nacho, BBQ. Can't eat anyone else's Taco...
Great Plains - Nothing like it anywhere
Pizza Pit - Friday night delivery
R Place (Kelley) - Some nice twists on the pie.
In Des Moines:
Casey's - Friday night carry out
Scornovaccas - Family recipe, in restaurant with onion rings appetizer.
