The wünderkind of healthy fast food has nine branches across central London and the City. All are wi-fi enabled. The Spitalfields branch gets very busy at lunchtime, but is a good place to go when quiet.
The wine merchants-turned-bar has 13 branches across the City and Canary Wharf. Unsurprisingly, clientele consists almost entirely of City workers, many of whom go there for breakfast (from 7.30am) and catch up their personal emails before the working day begins.
Le Pain Quotidien was established in Brussels in the 1990s and has become a hit with well-heeled Londoners since its arrival in the UK. Thirteen of its 15 branches have free wi-fi (Marylebone and Hampstead don't).
The 'Starbucks worker' has become a feature of everyday London life – more than 400 Starbucks coffee shops in the UK now have wi-fi access, with a good portion of these situated in London. If you want to get online for free, you'll need a Starbucks Card to access the Starbucks BT Openzone.
