Like the Bermuda Triangle, a slice of pizza is a hot wedge possessing mysterious powers of magnetism. Get lost in today's Groupon: for $10, you get $20 worth of pan-style pizza, calzones, and entrees at Jimmy's Famous Pizza in North Andover.

For more than 50 years, the chefs at Jimmy's Famous Pizza have dished freshly baked pizzas and entrees from a menu brimming with specialty pies. The Jimmy's Famous pizza heaps pepperoni, salami, sausage, and hamburger onto a thick-crust foundation ($16.95 for a large), and greek pizza sprinkles oregano and olives over layers of fresh tomato and feta cheese ($15.95 for a large). Munch on a dinner of fresh ziti, which adopts an orphaned chicken cutlet and bathes it in garlic butter or alfredo sauce ($8.95). Like suits of armor made of pumpernickel, steamy calzones surround meat with bread, cradling ingredients such as steak and cheese in a warm crust ($14.95 for a large). Large cold-cut subs can envelop sliced meats and cheeses between syrian bread or reduced-carb wraps ($5.75–$7.25).
