Proto's Pizzeria Gunbarrel Pizza ·$$

Pam Proto moved to Colorado in 1990 and immediately loved the Centennial State. Pam found her new home was everything she hoped for... except for one thing. She missed the pizza she had grown up with in New England -- the kind with thin, charred crust, bubbly cheese, and plenty of good memories. So she decided to bring that pizza to her new hometown. Today, Proto's is a Colorado-wide favorite. Guests will feel right at home when they're treated to a warm welcome from our staff (who are really more like family). After you've ordered, peek into our open kitchen and watch your pizza bake in our authentic Italian ovens. But hurry! In two minutes it'll be out and on its way to your table. Sit back with a glass of wine and enjoy your Proto's pie -- we promise you'll be delighted with every bite.

The food here was alright. I don't really have anything bad or good to say about the food, I just think maybe they should ease off of the oregano because the pizza just becomes kind of overpowered...
