Lewis and Clark, the bar chain founded by Steve Wilkins and John Connell after they sold Thomas & Carter is to launch three bars in London this month, the first of between 12 and 15 bars the company intends to open in the capital over the next 18 months.

The three bars, called respectively Prophet, Interval and Assembly, are all so-called "chameleon" bars, which are intended to appeal equally as pub, bar, coffee-house and restaurant. They were created by the design house Fusion.

Roger Gascoigne, the director of Fusion, said: "The client's brief was to create a rich, but relaxed environment where you'd be just as inclined to go for a business lunch as you would to go on a Friday night."

Three other sites designed by Fusion for another operator are due to open in Basingstoke this month.
