My first and only visit so far, May 2014. Ordered online 3pm on a Tuesday, delivered at 3:33. I live aprox 6 blocks away.
From a first time customer perspective the web site said I would get an email with delivery time and total cost, it never arrived which left me dangling as to if the order was even received. Half hour later I saw a truck pull up on the security camera. My tip was 20%.
I got a large custom with my choice of toppings, which I felt were a little sparse. I would compare this to Pizza Hut but say the pizza is one step below Pizza Hut, 'acceptable'. You can tell they don't put much effort into using quality ingredients, probably everything arrives frozen or canned in the store, and it shows.
This is like the McDonalds of pizza chains, poor quality but reliable service and results. And remember, on Yelp 3-stars means A-OK.
If you go to the Papa John's web site, then on About Papa John's, then on Ingredients and read the descriptions, I tend to doubt that my pizza was made from any of those ingredients.
