On the higher-price end of fast casual, with checks averaging around $16, this seafood chain trades on serving harbor-to-plate meals that are sustainably sourced. To convey an authentic shack feel, Luke’s touts its partnerships with other Maine-based vendors for everything—not only lobsters but sodas, microbrews and lumber used to make tables and counters. The chain is expanding beyond its NYC roots into urban markets, such as Chicago, Boston and Las Vegas, with plans to enter the South via Miami soon.
