LONDON, ENGLAND - JUNE 02:  Pub giant Greene King launches hot dog and burger flavoured ice cream to mark the start of summer long Burger & Hot Dog Festival on June 2, 2016 in London, England. The limited edition flavours will be testing the public's taste buds in city centre locations across London, Cambridge, Oxford, Liverpool and Manchester to see just how adventurous our culinary appetites have become. Pub giant Greene King, which is behind the social experiment, believes savoury ice creams could be the next big food revolution at mainstream restaurants and could be seen alongside the humble cheese board on pub menus up and down the country.
