The only way to cheer up a homesick fish is to tuck it into a bed of jasmine rice and lull it to sleep by humming the theme from Jaws. Soothe your deep-sea friends with today’s Groupon: for $15, you get $30 worth of fresh seafood and drinks at Fish On! in Lewes.

The friendly fishmongers at Fish On! lure in diners with a seasonally rotating menu of mid-Atlantic seafood, marbled steaks, and locally picked produce. Start by using pan-roasted mussels to win a mermaid bodybuilding contest ($9), and then take a victory swim in the shellfish- and lobster-populated tomato broth of the Lewes seafood stew ($24). Fish 'n' chips refine fading cockney accents ($17), and Bar Farms Delmonico steak acquaints diners with a hunger-fighting team of grilled asparagus and rosemary-potato cake ($25). Desserts such as apple pie with cinnamon ice cream keep sweet teeth from elongating into shark teeth ($6), and an international cascade of wine provides a tastier thirst-quenching alternative to saltwater.

The spacious dining room of Fish On! is graced with sleek wooden seating and pristine hardwood floors. Tableside fishing nets whimsically pepper the elegant atmosphere and come in handy for catching waiters trying to dash into the ocean with the cuisine.
