14. Sonic Drink Combos
Chain: Sonic Drive-In
Is there a bigger tease in fast food than Sonic? Its commercials advertise all over the country, but their locations seem few and far between. The adventure to find one, though, is totally worth it, especially for their mix-in sodas. The chain claims that there are “more than 168,000 drink combinations” possible. If you suffer from paralysis of choice, opt for the Cherry Limeade. It'll have you experimenting at soda fountains for the rest of your life, trying to get the proportions correct.
