Rocket Fizz

If you ask a child to draw the meaning of Christmas, there’s a good chance it would look something like Rocket Fizz. A step into Rocket Fizz is a step back in time—into a wonderland of old-fashioned candies and sodas that appear to be straight out of a kid’s imagination or a sugar factory’s family tree. The progeny of cofounders Rob Powells and Ryan Morgan, the shops—which have been mentioned on The Price is Right and endorsed by celebrities such as Snooki from _Jersey Shore_—burst with thousands of soda pops and candies.

Rob and Ryan created their own brand of pure-cane-sugar Rocket Fizz sodas, which tickle tongues in flavors such as banana nut, cherry cola, and apple jalapeño. Lester’s Fixins and Melba’s Fixins sodas—named for Ryan’s grandparents—offer sweet tastes of apple-pie soda or key-lime soda and adventurous flavors such as bacon soda and sweet-corn soda. Candy bars include classics such as Rocky Road, Bit-O-Honey, and Sky Bars, and bite-size candies include favorites such as Nerds, Milk Duds, and peanut-butter cookie-dough bites. Each shop also stocks nostalgic items, such as movie and music posters, gag gifts, and popular Jones sodas.
