TV chef Dylan McGrath has described how his staff were put through "a terrible and unfortunate ordeal" during an armed robbery at his Dublin restaurant that netted €10,000.
Raiders with a gun and knife threatened eight employees at the Rustic Stone, locking them in a room before the thieves escaped with the weekend takings.
The Michelin-starred celebrity chef was not in the premises, on South George's Street, when the robbery happened about 11.30pm last night.
But he has vowed the attack will not set back his business.
McGrath, who co-presents MasterChef Ireland, said: "This was a terrible and unfortunate ordeal to put the staff through.
"I am thankful that no one was injured, but upset that my hard-working team were subjected to this treatment last night.
"Myself and my business partners have worked really hard to make Rustic Stone a commercial success in this tough recession, and we will not be deterred by this incident."
The raiders took several mobile phones from the employees before fleeing with a substantial amount of cash, believed to be up to €10,000.
A Garda spokesman said no one was injured during the ordeal and appealed for information.
McGrath, who hosts MasterChef Ireland alongside restaurateur Nick Munier, opened Rustic Stone in August 2010.
RTE later announced the show will be back for a second series next month as the judges search for Ireland's best amateur cook.
