TV chef and restaurateur Antony Worrall-Thompson and a host of MPs marked the launch of the campaign - which aims to get people to 'Simply Ask' about food provenance when eating out - by signing a giant seven-foot egg at Victoria Tower Gardens. The number of people clicking through to www.freedomfood.co.uk/simplyask from online advertising in October and November were higher than the industry average. Adverts were carried on BBC Good Food, Channel 4 Food and Top Table websites. Freedom Food marketing manager Caroline Gauntlett said: "Simply Ask has got off to a really positive start. With more than 500 restaurants, cafes and pubs already signed up and calls from potential new members daily, it has far exceeded our expectations. "It is clear from the initial results we have found a campaign with which both restaurants and their customers can engage. It is proving to be a real recipe for success." However Gauntlett is keen to stress that there is still a long way to go with the majority of restaurants still using cage eggs. "'Simply Ask' isn't a quick fix solution. We recognise that many restaurants can't switch to using cage-free eggs over night. But we want those restaurants to start putting plans in place now to make the change to cage-free eggs by the end of 2010." Freedom Food is asking restaurants, pubs and cafes using cage-free eggs that want to support 'Simply Ask,' or are interested in phasing out cage eggs, to call 0300 123 0323 or email [email protected]
