There's nothing quite as satisfying as an old-fashioned milk shake made with real ice cream and served in a soda fountain glass with a metal mixing can on the side. At Avalon Diner, they've been doing it for years. Open since 1938, Avalon Diner is part of that dying breed of places that still boast a traditional soda fountain. Regular flavors like chocolate, vanilla and strawberry are always good, but you can also get banana, pineapple, butterscotch, Oreo cookie, mocha and Peppermint Patty. These cold and sweet confections are irresistible all year long.
