OK, a key to getting decent pizza here (assuming you walk-in) is to go while they are busy. If you go during off peak times your pizza will not be fresh since it's under heat lamps.
I will fully admit that part of the appeal to me is that I used to love this stuff when I was a kid. If you want to go here to eat in, check the coupon mailings sent to Madison households as they usually have Rocky's coupons. The regent locations has deals for slices and breadsticks after 8PM. The "Party Pizzaria" locations are nicer, with better decor, newspapers, games, etc. And of course, if you order a full pizza rather than a slice, your pizza will be fresher than being under a heatlamp.
