Lovefood is a popular online food platform that provides recipes, cooking guides, food news, restaurant reviews, and meal planning. They also make lists, which we love, so when it came down to listing the most unique dining experiences in the United States, one iconic spot was ranked 7th in the entire United States! Maine's oldest diner, The Palace Diner, in Biddeford, is housed inside an old Pollard railcar that was built in 1927. At The Palace Diner, everyone sits and eats in one line along the bar, just as they would if it were still a working rail carriage. If your travels take you to Biddeford, this is a Maine bucket list destination, that you have to try.
