I can only make suggestions in Pittsburgh. Primanti Bros, Wholley Seafood and Pennnsylvania Macaroni are all within a short block. If you want a real treat, go to Central Station. It is a very historic landmark. Many thousand troops passed through there, including my father during WWII. Maybe other Pittsburghers will join in here, but my honest opinion is to avoid Mt. Washington restaurants. Too expensive and overrated.
