Doorsteps

You're walking past the Marylebone high street crowds when you spot Doorsteps wedged between the usual suspects. This is the kind of place that doesn't need to shout about itself—the queue at lunchtime does that for you. They're doing straightforward, well-executed sandwiches that respect their ingredients: proper bread, quality fillings, and the kind of attention to detail that makes you realise how mediocre most sandwich shops actually are. The vibe is uncomplicated and efficient; you're in and out, but it never feels rushed. It's become the sort of spot locals deliberately seek out rather than stumble upon.
