The Evening Standard has launched a campaign, backed by the Mayor of London and Thames Water, to promote tap water in bars and restaurants. Ed's have signed us up for this - and can promise to serve water from the tap to any customer who asks for it, free of charge and without prejudice. Read about the campaign here:

Remember: Tap water is served FOC in a glass with ice and lemon. No questions asked!
