A plate of golden fried haddock, hot and crackling at the edges, can turn a random weekday drive across Pennsylvania into a meal you keep talking about weeks later. The best versions rarely come from fancy places.
They show up in chrome-trimmed roadside diners where the coffee is bottomless and the fish pieces are almost too big for the plate. Here are eight spots across the state where haddock earns its place at the counter.
