Gordon Ramsay Holdings is demanding that a new guide to the London eating-out scene is withdrawn and pulped after a member of staff noticed three errors about the group.
Ramsay's business partner, Chris Hutchinson, said the London Restaurant Guide 2004/2005 Edition: Eating and Drinking in Style contained some "horrendous errors" which he felt "completely negates its value".
The 160-page, £7.95 guide - published on 11 August by Scene It - mistakenly attributed Conran's Orrery restaurant to Gordon Ramsay Holdings.
Publisher Jeremy Mascarenhas accepted that this entry was wrong, and said the next batch of books would contain a correction and an apology.
"The guide contains 500 reviews of the most fashionable restaurants in London," Mascarenhas said. "Gordon Ramsay Holdings and Conran Restaurants are of such a high calibre, I would be surprised if either were that upset by any inaccuracy."
Hutchinson claimed that the guide also located chef Angela Hartnett at Claridge's, when she is actually based in the Connaught hotel, although it did print the correct street address.
But Hutchinson said his lawyers would be taking "extremely vigorous action" after receiving no response to two solicitor's letters.
