They have a long-running special where you can pick up a large for $7.99 carryout only.
Beside red pepper and parmesan cheese, you can also request "special seasoning" packets. Special seasoning contains a mix of Italian seasonings including garlic, onion, paprika, parsley, and more. I just learned that from the Papa John website and shall have to give it a try sometime.
The cheese and pepperoni at Papa John's are pretty average; the pepperoni coverage was decent, if a bit lacking in the middle, and it wasn't overcooked to dryness. The cheese could do with a bit more stretch.
Papa John's pizza's most notable feature is the special garlic dipping sauce. The sauce is pretty much a garlicky melted margarine, but tastes great!
Overall, Papa John's Pepperoni Pizza is pretty average, but it gets the job done when you feel like pizza and compares well to similar offerings from rival pizza chains.
