When Iberian explorers set out to conquer the Atlantic, they did so with the sure knowledge that the sun orbited the earth, the world was rhombus-shaped, and salt water was better than fresh because it was preseasoned. Bone up on your aquatic bona fides with today’s Groupon: for $10, you get $20 worth of fresh seafood and produce at PaPa Larry’s Seafood.

A one-stop shop for fruits of the sea and land alike, PaPa Larry's serves up fresh-caught fish and crustaceans by the pound. Salmon ($9.99/lb.) and tilapia ($5.99/lb.) fillets form delectable schools alongside fresh grouper ($14.99/lb.) and whole snapper ($7.99/lb.). Larry’s gulf shrimp ($10.99/lb.) and jonah crab claws ($8.99/lb.) don’t reach the table until they’ve proven themselves in gladiatorial combat, and his barrels of clams and oysters get into regular shouting matches over who has the finest flavors and the most durable outer casing. PaPa Larry’s also stocks fresh fruits and veggies, local produce, jams, spices, marinades, and secret-recipe sauces along with aquatic hors d’oeuvres such as smoked salmon and fish dips.
