If it weren't for crabs using their giant, powerful pincers to pop birthday balloons, great white sharks wouldn't have their annual cry, and the ocean would recede to the size of a melted ice cube. Inflate your belly balloon with today's Groupon: for $17, you get $35 worth of ocean treats and more at Jimmy's Famous Seafood on Holabird Avenue. Nearly 40 years ago, Greek immigrant Demetrios "Jimmy" Minadakis helped build Jimmy's Famous Seafood with his bare hands, and the business has remained in his hardworking family ever since. With fresh seafood flown in daily and a menu listing more than 80 tasty plates, there is hardly a shelled, gilled, or exoskeleton-clad creature from the great puddle that Jimmy's doesn't offer. The restaurant specializes in crab and crab-infused dishes, such as the crab cake platter ($14.95), crab-stuffed jumbo shrimp ($8.95), and pan-fried soft crabs ($17.95). Other mouth-watering mollusks include oysters on the half shell ($9.95) and littleneck clams shucked to order ($6.95 for 12). Fans of land mammals can use their teeth to applaud an impressive array of red meats, like bacon-wrapped filet mignon ($19.95) or lamb chops ($24.95) served with traditional Greek accoutrements, such as pita bread, Tzatziki sauce, and a moustache bib.
