Bar Italia

There aren't many London coffee shops open from 7am until 4am seven days a week, and that near-round-the-clock schedule makes this Mayfair/Soho spot a genuine outlier — as handy for a morning brew as for a post-midnight caffeine fix. Takeaway, dine-in and outdoor seating are all on offer, wheelchair-accessible seating is available, and a 4.2 rating from more than 2,000 reviews speaks to a dependable following.
