B2R, if you had bothered to read the link you might learnt that coffee houses are an important part of British history. Since the 1600's, coffee houses have been seats of learning and business. The London Stock Exchange started in a coffee house, as did the Lloyds Shipping Register, and the auction houses Sotherby's and Christies.
And all rather before any American influence..... The list is endless, but just one example:
In 18th century, Dublin coffeehouses functioned as early reading centers and the emergence of circulation and subscription libraries which provided greater print access for the public. Coffeehouses were a culture symbol where different worlds came together to discuss topics of the newspapers and pamphlets. Most coffeehouses during the Eighteenth Century were equipped with their own printing presses or resided by book shops which most would later merge with for better business. (From Wikipedia)
However, if you require the history of pubs, I suggest you read Pete Brown's excellent books.
