After properly cooking a lobster, its once-brown exoskeleton turns bright red, letting chefs know that it's both ready to serve and profoundly embarrassed for showing up without pants. Make a meal of deliciously mortified seafood with today's Groupon: for $4, you get $8 worth of lobster rolls, hot dogs, and ice cream at Lobster Shack, located at Jessica's Garden in Marlborough.

Jessica's Garden treats flora fans to fresh, casual eats that can be savored on the garden center’s lush landscape. Extend clapperclaws to the buttered lobster roll, a quarter-pound of crustacean nestled in a grilled New England-style bun ($9.99). Lobster-lovers can order it Connecticut-style, served with warm claw and knuckle meat, or Massachusetts-style, in which chilled lobster meat mingles with mayo and diced celery on an honorary Harvard diploma. Grilled cheese ($2.99), hot dogs ($2.99), traditional New England clam chowder ($3.99 small, $6.99 large), and lobster bisque ($4.99 small, $7.99 large) satisfy savory palates. Homemade ice cream in unique flavors including goat tracks—vanilla ice cream with chocolate chips, peanut butter, and peanut butter cups ($2.25+)—appeases persnickety sweet teeth and makes for a straw-challenging milkshake ($4.99). Take advantage of this seasonal establishment's BYOB policy and fair-weather eats, which diners can devour near an on-site bass pond or an off-site bass player.
