It’s hard to find great crawfish in Dallas outside of a backyard boil, but Shells & Tails has nailed it. This creole and cajun food truck has a small menu that includes boiled crawfish, snow crabs, and shrimp, plus a few other things like seafood nachos, rum cake, and pralines. They’re based in DeSoto but don’t have a permanent spot, so make sure to check their Instagram for their daily location.
