Color me one to go against the grain here. I love Papa John's pizza. You said it was soggy. Perhaps you may have just gotten a bad pie? I always ask for our pizzas (from all places) to be made 'well done' as we like the crunchiness of a pizza that is a little more done.
Occasionally, we'll get a pizza (from all places) that doesn't live up to expectations, but I don't refuse to go back there based on a one-off experience.
