DownEast: The 30 Best Burgers in Maine

Some 200 miles and a culinary universe away from the patty melt at Al’s Diner, Primo grinds its own blend of grass-fed beef from Maine’s Cold Spring Ranch, then stacks up two 4-ounce patties topped with aged gruyère, caramelized onions, and a special sauce that blends house-made mayo and hot sauce. 

Thank you Joe Ricchio! We love our Patty Melt too!
