You're by the seaside: it has to be done! Rick Stein's Padstow chippie is as good as you'd expect, with a choice of locally caught fish served with proper chip-shop chips.
Go for the take-away option, and enjoy a box of fish'n'chips perched on a bench by the harbour (watch out for gulls). Drench them with vinegar, and eat them with a wooden fork for a real nostalgia trip. Alternatively, find a table in the informal chippie restaurant (just remember that you can't book this).
Stein's works with Momma Bains to create perfect Punjabi dishes, because curry has long been a staple of the best fish and chip shops. Pop back in for a Treleavens ice cream to finish off this textbook seaside meal.
