At soda jerks, one can make any soda selection into a float. My personal favourites are red birch beer and dandelion burdock, the latter of which prompted a waitress to once ask if I was 'really sure' that's what I wanted. Yes, it is. It's delicious, loaded with ice cream and dandelion flavour, thick and thirst-quenching. Try it out!
