Avocado & Coffee Organic Cafe in London

The clue is in the name: this Greenwich café puts organic food, avocado and coffee front and centre, and a solid 4.2 from more than a thousand reviewers suggests the formula works. Doors open from 7 AM six days a week — 8 AM on Sundays — and it's a notably inclusive spot, welcoming dogs and offering wheelchair access from the entrance right through to the seating and toilet.
