Mackbear Coffee Co. UK

Open from 6am until 11pm every day of the week, this Whitechapel/Spitalfields spot runs hours most cafés can only dream of — as good for an early-morning espresso as for a late-night pastry. The counter leans firmly towards the sweet side, covering patisserie, desserts, confectionery and bakery treats alongside its coffee, with outdoor seating and step-free access throughout. It's also one of a small cluster of Mackbear sites around east London, with further locations in Stepney Green and East Ham.
