The self-described 'modern seafood shack' made its debut in the capital last year with a focus on serving sustainably-sourced fish.
Davis Coffer Lyons is marketing the 870sq ft site on Kentish Town Road in Camden, which holds between 15 and 20 covers.
The annual rent on the site is listed as £50,000.
Reputed to be one of the largest fast casual seafood restaurant chains in the US, Slapfish's UK menu featured a selection of dishes available in the US including lobster meat mixed with melted butter, mayonnaise and lemon and served in a brioche bun; fries topped with New England clam chowder and bacon; and an ‘ultimate’ fish taco topped with cabbage, pickled onion and house sauce.
Slapfish was founded by American chef Andrew Gruel in 2011 as a food truck operating in Los Angeles and Orange County with a menu of just three items.
In 2012 Gruel opened Slapfish’s first bricks and mortar restaurant in Huntington Beach, California, and has since expand the business across the country.
It now operates more than 20 sites across 11 US states.
