Illy Caffè, London

Open from 6:30 in the morning until six in the evening, seven days a week, this Bermondsey/Waterloo spot takes its early starts seriously — a blessing for anyone after a proper breakfast first thing. As the name suggests, coffee sits at the heart of things here, with both dine-in and takeaway service at comfortably moderate prices. A step-free entrance and wheelchair-accessible seating make it easy to settle in, and a steady 4.3 rating from 393 reviews suggests plenty of people do exactly that.
