With over 38 years in business, William Dugan earns his nickname, "The Fish Guy." Although Dugan sources domestic seafood whenever possible, he is willing to look as far away as Portugal or New Zealand in the name of quality. His one unwavering rule is to work exclusively with small, family-run businesses who value sustainable, environmentally-friendly fishing practices. Dugan stocks his market with an ever-changing selection of fresh, seasonal catches that can include anything from Cape Breton lobsters, Illinois sturgeon caviar, and Green-certified King Salmon. Wellfleet, the cafe within the store, offers a lunch menu with clam chowder, salmon burgers, a clamwich, lobster rolls, and other seafood staples. Even Chicago restaurants endorse Dugan's quality catches. The Fishguy Market's wholesale division has supplied local Michelin-starred eateries such as Alinea, Ritz Carlton, Moto, and Grace, as well as newcomers Parachute and The Duck Inn.
