I visited on a Sunday evening during a Steeler game, the place was semi full but in no way packed. I will start by saying this place would receive 5 stars if it was solely based on service alone. Our server, Allen (if I recall correctly), was helpful in explaining items on the menu and really made us feel welcome.
I was in a party of five (lol) there celebrating a birthday, it was the first trip to Proper for all of us. We started with the house chips and French dip. They made for a great start to a meal unfortunately the rest of the meal didn't live up the appetizer.
I ordered the Margherita pizza, others ordered the pesto pasta and pesto pizza. I wasn't too pleased with the pizza. Honestly for $15 I expected something more filling and satisfying. The pizza itself was burnt, now I know it's brick oven pizza but it lacked flavor. The middle of the pizza itself was very soggy and once it cooled it tasted half cooked. Not sure if the oven was up too high or too many pizzas were placed in the oven causing it to be cooked unequally.
A friend who ordered the pesto pasta wasn't happy with her meal either, it was too oily and not what she expected. Those who got the pesto pizza however were very happy with their choice.
The bathroom was a mess with toilet paper and paper towels covering the floor. I bet this was the cause of Steeler fans eating prior to the game but we didn't arrive until after half time so that's more than enough time to clean up.
Between the less than stellar food and messy bathroom this place gets three starts from me. I would consider coming back on the service alone but will definitely order something besides the pizza.
