Mr Jordan has left the Cow and Lobster to concentrate on his other venture Mark Jordan on the Beach, Mr Ruff has said.
The Cow and Lobster has since closed but Mr Ruff said it will reopen shortly following a rebrand and a ‘menu overhaul’.
In a Facebook post, Mr Ruff said: ‘You may have seen that our team have been busy taking down the signs at the Cow and Lobster over the last few days and I am sure you are wondering why.
‘Unfortunately, Mark has decided to leave the Cow and Lobster to focus on his other restaurant and as all the signage says “Cow and Lobster Mark Jordan” we had no choice but to take the signs down.
‘So instead of redoing the signs by taking Mark’s name off them we have decided to rebrand completely and carry out a menu overhaul based on the feedback we have received over the last few months.
‘We don’t plan on being closed for long and we will keep you updated on the changes that are being made.’
Mr Jordan was unavailable for comment.
