The line between pubs and cafes is becoming less clearly defined

Greene King will put Coffee Republic machines in 28 of its London pubs as the company looks to broaden the range of drinks it can offer consumers.

The pub industry is undergoing a period of radical change as opening hours are extended and smoking bans are enforced.

As a result, many pubs are looking to offer more food and softer drinks.

'Dusty cups'

Coffee Republic said that while many pubs have previously offered coffee and tea, they have not always been of the high quality that consumers expect today.

"People won't accept that dusty old coffee anymore," said Steven Bartlett, a spokesman for Coffee Republic.

He added that people were willing to pay �2 for a cup of coffee but only if it was a premium product.

Coffee Republic already has an agreement with retailer WH Smith, where it provides drinks in some of the firm's shops.

Mr Bartlett said the company was looking to increase the number of partnerships it was involved in.

Other coffee companies have also examined ways of boosting their range of offerings.
