La Grande Mare managing director Simon Vermeulen said the success of the cut-price food bonanza had convinced him to extend the three courses for £10 offer until the end of the month.
'It has been our best Tennerfest year ever, we have done 3,000 more covers than last year. We are getting a lot of people dining with us more often and our reputation is shining through.'
And it is not just La Grande Mare which is seeing the benefits either, as another dozen restaurants are giving diners until 30 November to snap up a bargain.
