The initiative, designed to help boost tourism across the borough, will feature a strong variety of restaurants in South Shields, Jarrow, Hebburn and Boldon.
Visitors can choose from independent bistros, high street chains and riverside pub retreats, each offering their own discounts and offers for the rest of the week.
Councillor Alan Kerr, Deputy Leader of South Tyneside Council, with responsibility for Culture and Leisure, said: “There are more than 28 venues taking part, not only offering a wide range of foods but participating from right across the borough.
“We hope that this will encourage diners from South Tyneside and further afield to take advantage of the special offers available until Saturday and to come and sample some of the fantastic cuisine that the borough has to offer.”
Colmans, the award-winning Fish and Chip shop in South Shields, which has been running since 1929, is also participating in the event.
They will offer a starter of tempura crab claws and a main of smoked salmon and dill fishcakes.
Colmans owner Richard Ord said: “Neither of these dishes feature on our menu, so this will be an ideal opportunity for visitors to come along and try a new combination of flavours, as well as some fantastic North East seafood.”
Councillor Alan Kerr, also said: “Colman’s is one of South Tyneside’s longest running food businesses and we are absolutely delighted to have them on board for our first ever Restaurant Week.”
South Tyneside Restaurant Week is organised by South Tyneside council and runs until Saturday October 10.
Other eateries taking part will offer a discounted two- and three-course set menu for its punters to enjoy across the seven day culinary event.
