First off - I am a Philadelphian but whenever I visit the Steel City, Wholey's is a must. My favorite is the fried fish sandwich and the lobster mac and cheese. Recently I tried the clam strips, oh they were so fantastic. My husband, a native Burgher, is all about the Shrimp Po Boy.
Second - the bread, oh that bread is wonderful, it adds so much character to an already awesome sandwich with super fresh fish.
Lastly - portion size, I am full when I leave. they give huge pieces of fish.
