Pier 76 Fish Grill is a seafood restaurant in Long Beach. It’s built into the ground floor of the historic Cooper Arms building. It’s a pay-at-the-counter, quick-service, moderately -priced seafood restaurant modeled in the same spirit as California Fish Grill. The dining room is barely a room at all, with butcher-block tables and a cramped space no bigger than most Subways. On sunny afternoons, most of its customers choose to sit outside in the gorgeous patio surrounded by a garden and the soaring apartment building. But as evidenced by the mussels and a live lobster he grills with roasted garlic butter, owner Chris Krajacic is aiming higher than the fast-casual his restaurant appears to be—much higher. He joins Slapfish’s Andrew Gruel’s and Roe Restaurant’s Arthur Gonzalez in that seafood-restaurant sweet spot between the California Fish Grills of the world and the Scott’s Seafoods and Mastro’s Ocean Clubs. Try his mussels, the best you’ll ever likely to have anywhere.
