Pizza and cheese steaks near the Prince Theater
Bigley what time of day? Comcast Center food court has both. Directly connected through Suburban Station. Mike's Steaks is good, LaScala Pizza is acceptable, and available by the slice. You also have Mexican Post, Under the C, DiBrunos, Sushi, etc there. I think most are open until 7pm.
Ray's comment about Steve's is spot on though the place is small, and really is more designed for take away.
