Fountain Valley-based Slapfish Franchise LLC plans to add three franchised OC locations of the fast-casual seafood restaurant chain to the four it has opened or planned here.

The new deal is for three restaurants from franchisee Doug Pham. Pham has a lease signed for the first one in Brea, and has reserved Corona del Mar and the Irvine Spectrum area with the franchisor for the other two.

Slapfish started as a food truck in 2011 and opened a Huntington Beach location in 2012. It began franchising the following year and has added locations in Laguna Beach, Newport Beach and, in July, in Irvine.

Huntington Beach and Laguna Beach are company-owned sites; Newport Beach and Irvine are franchised locations.

In 2013 it said a franchisee would open 75 locations in the Middle East; one has opened so far.

It also has locations planned at Los Angeles International Airport and at Baltimore-Washington International Airport.

The chain was cofounded by Andrew Gruel and Jethro Naude, the latter of whom has left the company, and applies fast-casual and sustainability trends in food service to seafood, with a menu including French fries topped with clam chowder, and the “Clobster” grilled cheese sandwich, which adds lobster and crab to the comfort food staple.

A Slapfish franchise costs about $500,000 to open, according to the company’s franchising documents; a multiunit franchise agreement includes about $105,000 in franchise fees, depending on the number of units planned. Royalty and marketing fees total 8% of gross sales.

A single location franchise fee is $30,000 according to the comapany, with the same royalty and marketing fees.

Slapfish works on franchising through the Newport Beach office of Alexandria, Va.-based franchising consultant Fransmart.

New franchisee Pham operates a franchised location of Newport Beach-based zPizza in Ladera Ranch; zPizza is also a Fransmart client.
