Lava cafe

Open from 7am until 3am every single day of the week, this South Kensington coffee shop almost never closes its doors — a genuine rarity in a city where most cafés wind down by late afternoon. Dogs are welcome, the entrance and seating are wheelchair-accessible, and there's outdoor seating alongside dine-in, takeaway and delivery options. A 4.3 rating from more than 130 reviews suggests it's doing something right.
