First up: Indian restaurants. Seriously, this is a London Christmas tradition that non-locals often miss. Places like Dishoom in Covent Garden and Bombay Bustle in Mayfair throw open their doors, serving steaming biryani and buttery naan to anyone who needs a break from turkey. Yes, you’ll have to book ahead—don’t you dare show up without a reservation, or you’ll be weeping into a cold mince pie.
For a more classic vibe, pub lunches are a thing, but only at specific spots. The Grenadier in Belgravia and The Churchill Arms in Kensington often do a Christmas Day roast—think crackling pork, roast potatoes, and enough gravy to swim in. But check their websites first, because many pubs now require tickets bought weeks in advance. (Pro tip: if you’re reading this on Christmas Eve, you’re probably too late for a roast, but don’t lose hope—see next point.)
If you’re just after a coffee and a pastry, Costa Coffee and Pret a Manger at major train stations (like King’s Cross or Paddington) stay open for a few hours. It’s not glamorous, but a flat white at 10 AM on Christmas Day feels like a miracle. And yes, you’ll find a handful of McDonald’s and KFC in central London open too—perfect for when you’ve had one too many sherries and crave a salty, greasy disaster.
