Get a fresh-made waffle or shake with your pick from a variety of sauces (chocolate, white chocolate, apple, cherry-and-strawberries etc), fruits (cinnamon-coated apples, strawberries, kiwi, bananas etc) and toppings (chocolate chips, dried coconut shavings etc). Top it off with some Oreo cookies or a dollop of ice cream or sorbet for some real decadence.
