A large piece of battered, fried fish that hangs well over the bun, a Catholic Lenten staple that runs year-round. Church fish fries and old market counters both serve their own versions.

Pittsburgh's heavily Catholic, Eastern-European population made the Friday fish fry a fixture, especially during Lent, when parishes and fire halls battered and fried cod by the hundreds. The habit spread to year-round counters: Wholey's in the Strip District has fried its famous oversized fish sandwich for decades, and The Original Oyster House on Market Square has served fried fish since 1870. The sandwich is judged by how far the fish overhangs the bun.
