Big crispy portions flopping on big oval plates eaten with a big knife and fork to big 1950s sock-hop music: The franchise-ready Poppies does for British fish-and-chips what peppy jukebox diners have done for mid-20th-century American food. For all its plastic theatricality, it hews to authenticity: The chief dish, cooked to order, is sustainably caught and sourced. For those whose palates swerve differently, there’s also chicken, the chance to try jellied eels (be afraid), and strong drinks.

Try the Soho location (55 Old Compton St., W1; 020/7734-4845; same hours) for strolling the West End with chips.
