Founders Tim Haigh and Rupert Pendered will launch the restaurant on 14 September.
The restaurant, which started out as a street food stall in Berwick Street Market, will serve its signature menu of Cornish fish, served either grilled, battered or breaded, served with beef fat chips.
It will also serve the likes of fish pie; fishcakes; cod Scotch egg; and salt and pepper squid.
Non-fish dishes are also available, including a beef burger; deep fried halloumi with tzatziki; and superfood salad with butternut squash, broccoli and freekeh.
Traditional sides such as chunky chips and pickled eggs sit alongside the likes of Asian slaw; and avocado salad on the menu.
The Chipping Forecast prides itself on the relationship it keeps with its fisherman, many of whom are pictured on the walls in the group’s Notting Hill site. The fishermen use sustainable fishing practices, and the restaurant guarantees “hook to plate within 48 hours”.
Haigh and Pendered are not the only seasoned restaurateurs to choose this autumn to take a bite out of the fish and chip market. Edinburgh-based Vittoria group – known for its refined group of Italian restaurants – is set to launch a 270-cover fish and chip restaurant in the city’s Old Town.
