Lever & Bloom Coffee

Home of the viral giant cinnamon bun — a £29.99 showstopper that needs ordering a full 24 hours ahead — this Bloomsbury bakery has clearly won people over, with a 4.9 rating from 928 reviews to show for it. Day to day, it's artisan coffee and handmade buns doing the talking, with takeaway and delivery on hand for those on the move. A wheelchair-accessible entrance rounds things off nicely.
