Try their chipotle pizza sauce - yum. Love their thin crust pizzas - also fun watching them make the dough. Small but quaint location.

I have always gone to Proto's during the lunch hour but have NEVER been disappointed in the speed of service, hotness of my pizza, freshness of my salad, friendliness of the staff. All entrees I have eaten have been excellent. Great menu variety. Located on the quieter west side of Longmont, Proto's is easily accessible from popular local thoroughfares Airport... More

So, I hate writing negative reviews about local places but- I either had unfortunate below average experiences or this pizza is over-rated and somebody needs to give a reality check to Proto's. Both experiences were less than fresh toppings. Literally canned stewed tomatoes on the Margarita, I had to look for cheese and I like my cheese light, and barely... More

Proto's Pizza is my favorite pizza in Longmont, CO. Each time I visit my family & friends there I have to have this pizza! My favorite is the cheese pizza & dip the slices in balsamic vinegar & olive oil. It's got a different texture and, being diabetic, it has a thinner crust and the amount of cheese helps keep...

Traditional, authentic pizza. That is to say not your cheese and topping heavy American interpretation .If that's what you like, fine but don't come to Protos, stick with Blackjack or Pizza Hut or what have you. Cute bar area with a good selection of beers, including local brews and they make nice cocktails, too. Unfussy and casual and we love... More

I really enjoyed the pizza with sausage and bay leaves. I am allergic to preservatives and they make everything fresh. Their sausage and prosciutto is imported from Italy and does not have preservatives either. The staff is friendly and efficient.

I was really excited about trying this place after reading the great reviews. I drove over from our hotel to pick it up since they do not offer a delivery service. I saw they make gelato as well so grabbed a pint of their cookies and cream. Total bill was around $30 for a single large and the gelato which... More

Many business trips to the UK ended up with at least one meal at a Pizza Express restaurant. When we discovered Proto's Pizza we felt very much like Pam Proto had nailed a vibe very similar to Pizza Express. Since that first time in 1999, we have dined at Proto's numerous time with friends, family and business associates from the... More

Proto's is owned by the same folks who run the Boulder Proto's. They are originally from Connecticut which has the best pizza in America, and they know what they are doing. We usually share a caesar's salad, always good, and get a sausage - extra cheese pizza. The pizza is thin crust and cooked perfectly. Highly recommend Proto's.

Stayed in Firestone CO on return trip from Yellowstone. Not many local food places nearby so searched for surrounding area. Most were 30 minutes away, but found a recommendation for Proto's pizza less than 20 minutes away. Little hard to find even with GPS. On back side of shopping center that fronted Airport Road, in residential area. Best landmark is... More
