A high-protein diet can help build muscle, which comes in handy for fighting off a shark that is also on a high-protein diet. Take a bite out of the circle of life with today's Groupon: for $10, you get $20 worth of American cuisine and drinks at Jennings Cafe in Catonsville.

Jennings Cafe's epicurean curators craft an immense menu from family recipes that helped earn it a spot on the Baltimore Sun's 2009 list of Top 10 All-American Restaurants, and staff members deliver dishes with Zagat-recognized service. Crunch into a combination of fried openers on the Superfecta platter piled with classics including mozzarella sticks, breaded mushrooms, and chicken tenders accompanied by a cadre of dipping sauces ($10.95).

A 50-year-old family recipe sets jumbo-lump-crab-cake sandwiches (market price) apart from their small-morseled competitors, and chefs crisp seasoned cakes with your choice of a broiler or fryer. Let full-portioned entrees such as the juicy Delmonico steak ($16.95) quell meatier appetites, or bite into the comestible comfort of a melty grilled cheese ($4.95) with bacon ($0.75 extra). Other options on Jennings Cafe's trailing list of eats include wraps, club sandwiches, pasta, and pizza. Warm lighting, wood accents, and the glow of sports-filled flat screens bathe Jennings's ample bar seating in a classic pub atmosphere.
