The ladies head down memory lane to the days when it was all about the soda shoppe, the jukebox, and a good ol' rootbeer float. They serve you up three retro desserts you'd find at a diner or a lunch counter. Emily starts with the ultimate diner delight, a grasshopper pie. Daphna bakes a kitschy and cool checkerboard cake. And Elizabeth goes for decadence with a chocolate wafer torte, full of whipped cream.
