Pop's Four Cheese + Pitcher of Shiner = ganador!
I can't think of anything in Waco that's as ridiculously cheesy as the Pop's Four Cheese pizza here. I'm talkin' gooey, wonderful, "does this ever quit stretching out into longer strings of cheese and actually separate itself from the rest of the pizza?" kind of cheesy. It's fantastic. Rollo's has some other good specialty pizzas, but the Pop's Four Cheese is my usual.
The interior is...well, kinda dark and dirty. There's stuff everywhere, and it always looks a tad dusty--enough so that even I notice that it's dusty. But, hey, I'm not eating the decor, so as long as it doesn't fall into my food, I can't complain too much.
