Owner David Conger has worked as a commercial fishmonger for most of his life. He operated in Rowlett for four years before moving to Plano in 1994. His shop offers at least 20 fresh species every day and close to 120 frozen varieties. The shop sells more than 8,000 pounds of crawfish per week during the busy season (January until the Fourth of July). Dave’s also sells premade crab cakes, 16- to 20-count Cajun-style shrimp steamed daily, and in-house smoked salmon. The staff will vacuum-pack your fish for freezing, and the store offers crawfish cookout party services.
