Everyone in town raves about Primanti's. However, this has to be my more favorite place to stop while in Pittsburgh. They have an awesome menu (cash only) but you cannot leave and not get the Roethli"burger". Delicious. Yum. Heck to the yes. I love the small kitchen style atmosphere, and they love it when you tip. I mean, they go nuts when you do (Ala Cold Stone singing style nuts). Great people, even better food. Come hungry!
