Caravan Canary Wharf

Open from 7am on weekdays and serving well into the evening, this all-day restaurant on Reuters Plaza takes Canary Wharf from breakfast and brunch through to pizza and cocktails. Coffee is a serious business — Caravan roasts its own single origins, which you can also take home by the bag — and the menu keeps vegetarians well catered for. Throw in outdoor seating, wheelchair access throughout and a 4.7 rating from nearly 3,000 reviews, and it's easy to see the appeal.
