Restaurants of star chefs on the list of the Harden restaurant guide

According to Harden's London Restaurants 2015 guide, celebrity restaurants 'are showing signs of difficulty in keeping the quality high as they try to grow their restaurant empires'.

Restaurants run by celebrity chefs such as Heston Blumental and Marcus Wareing have been classed as some of the most overpriced, worst food among the top London restaurants.

According to Harden's London Restaurants, whose 2015 edition is published on Thursday, London’s restaurants are “in overdrive” with the highest ever rate of net new restaurant openings in the capital recorded.

But the guide's co-founder, Peter Harden said some celebrity restaurants were become victims of over-rapid expansion and the quality had suffered as a result. (MTI)
