In Pittsburgh there's a ton of pizza places, but Papa D's is by FAR the best. The drinks are cheap and the food is awesome. I would willingly sell my left arm for their famous tomato anchovy apple pie with a scoop of homemade limoncello ice cream. If you've never had it before, you're not a true yinzer. And there's this one bartender named Angie (or Angela?) that  makes my drinks strong, and speaks absolutely immaculate Korean.  Seriously, go in just to have a conversation with her in Korean, she loves it. Highly recommended!
