The Fish & Chip Company in Bromley will serve up 99p portions of cod and chips later this month.
The Hastings Road food outlet is offering the discounted treats on May 17 to celebrate Norway Day, with help from the Norwegian Seafood Council.
A total of 16 tonnes of cod has been gifted to 99 shops across the UK as part of the initiative, allowing nearly 40,000 people to join a celebration of the nation's favourite dish.
Cem Selchouk, from the Fish & Chip Company, said: "We are so pleased to be taking part in this annual celebration.
"Fish and chips are a firm favourite in Bromley; I know that our customers will enjoy the delicious Norwegian cod and chips on offer - and they will certainly enjoy the prices too!"
