The sea has much to teach us: its tides foretell the lunar cycle, its salt treats us to delicious shark jerky, and its colorful creatures prove that nature looks better in Blu-ray. Celebrate the big salty puddle's sagacity with today's Groupon: for $20, you get $40 worth of fresh seafood, savory steaks, and more at Riverside Steakhouse & Oyster Bar, located on Person Street. Recently recognized by The FayObserver for its tranquil ambience and satisfying sustenance, Riverside Steakhouse & Oyster Bar offers roaming packs of ravenous diners hearty, homey meals. Start with a toasty bowl of soup, a crisp salad, or a sharable small plate, such as steak tips and fries ($9). For dinner, dive fork first into a sea-borne entrée, like the pan-seared honey citrus salmon ($16) or the fried flounder with three-cheese macaroni and local veggies ($14), as your ears sop up the sounds of live music. Ogle the full menu before heading to Riverside with a close friend, family member, or recently laid-off superhero for a mood-boosting feast.
