London has a habit of turning forgotten bits of street furniture into something better, and the latest example is on Holloway Road in north London. A former ATM has been given a second life as a tiny dessert window serving tiramisu at £4 a portion — a conversion that's turning a machine people once used to withdraw cash into one where they now spend it on coffee-soaked pudding instead.

The idea is delightfully simple. Rather than letting the defunct cash point sit as dead street frontage, someone has knocked it into a walk-up hatch where passers-by can grab an Italian classic to go. There's no seating and no fuss — you order at the window and walk off with dessert in hand, which suits a busy stretch like Holloway Road where most people are heading somewhere.

Why should a traveller care? Because it's a perfect illustration of what makes London's neighbourhoods worth exploring beyond the obvious centres. Holloway Road sits along the A1 corridor in Islington, a couple of stops up the Piccadilly line from King's Cross, and it's packed with the kind of independent shops and small food operations that never make the guidebooks. A tiramisu window in a disused cash machine is exactly the sort of thing you stumble on when you walk a few streets away from the tourist trail.

It also fits into a wider trend across the capital: small operators taking over tiny or unusual premises — old public toilets, former ticket booths, closed banks — and turning them into coffee stands, wine bars or sweet shops. For visitors, that means the best food finds are often the smallest, cheapest and easiest to miss. £4 for a proper tiramisu is firmly on the right side of London prices, especially compared to dessert menus at nearby restaurants.

Practically speaking, it's an easy add-on to a day out. Combine it with a wander through Islington, a stop at nearby Camden Passage for antiques and cafés, or the canals and markets around Angel. If you're staying anywhere near King's Cross or Finsbury Park, you're minutes away. Go with modest expectations about queueing space — it's a window, not a restaurant — and treat it as a sweet pit stop rather than a destination in itself.
