I don't get seafood all that often, but Joe's Crab Shack on the Wilmington Riverfront is a pretty decent place. There's also the Blue Crab Grille in Newark's Suburban Plaza, and another place on the Riverfront, though I forget the name. It's right by Joe's and Iron Hill, near where Kahunaville used to be...a bit higher-end and pricier, but very very good.
