Alyn Williams, Ben Spalding, Jose Pizarro, Mark Poynton and Mickael Weiss will work alongside Michelin-starred chefs Russel Brown and Phil Thompson to create a one-off menu at the Floridita restaurant in Soho on 30 April.
The money raised will allow the CALM (Campaign for Living Miserably) helpline to run to 3am every night of the week. Once the charity’s target amount is reached, the money will be split with the fund being set up by the Boyle family in Kevin's memory, to help young men suffering from depression.
"We want to send a message to those in the industry who are struggling with depression that it's OK to ask for help,” said the event’s organiser Dave Ahern.
A number of high-end London restaurants, including Jason Atherton's Pollen Street Social, Galvin at Windows and Alyn Williams at the Westbury, will donate front-of-house staff for the dinner, which will be hosted by comedian David Baddiel.
The event is being filmed for broadcast on the Tonight show on ITV 1 at 7.30pm on 3 May. Tickets are priced at £200 a head and are available from www.skiddle.com.
