Square Mile pours the house espresso, but the guest roaster programme is the reason to come back. Batch brew is on and made with the kind of acidity-awareness that tells you someone here is paying attention.

Square Mile anchors the espresso, a guest programme that actually rotates.

What we love

  • Square Mile Coffee Roasters on house espresso
  • Active guest roaster programme, one of the longer-running in London
  • Batch brew available, made with flavour-awareness rather than just convenience
  • Flat whites and cappuccinos consistently well-regarded across hundreds of reviews
  • Strong food offering; banana bread, pastries, sandwiches; if you're staying

Gramos Coffee Bar★★★ Purist

Down a stairwell inside King's Cross station, past the ticket hall and the Harry Potter shop, sits a full roastery-run espresso bar with beans rotating by the week. Tell the team what you're after and they'll point you to the right cup.

Hermanos Colombian Coffee Roasters★★★ Purist

Their own Colombian single-origins, roasted at the brand's own roastery and traceable to named producers, poured from a takeaway kiosk by the station. It's the kind of pedigree you don't expect from a coffee grabbed on the way to a train.

Frequency Coffee Kings Cross★★ Specialty

A short walk from King's Cross station, worth the detour when the alternative is a station-chain coffee before your train.
