"What’s old is new again at Palace Diner. When Chad Conley and Greg Mitchell reopened this restaurant as its sixth owners in 2014 in a 1927 Pollard train car, they captivated critics and catapulted Biddeford, Maine — a former mill town 20 miles south of Portland — into the national dining spotlight. At a glance, the setting and menu read like any other cozy slice of Americana across the country. But you don’t need the fog of nostalgia to fall hopelessly in love with Palace’s tuna melt, layered with an inch of crunchy iceberg lettuce on grilled challah, or its pancakes, unbelievably buttery and light. These days, you can even order takeout online, which is great news since this diner only seats 15. — Adam H. Callaghan" - Eater Staff
