I found Candyland! Dylan's Candy Bar originated in New York City and I was lucky enough to visit the multilevel masterpiece back in 2005. I believe in candy and color and fun - all things that can make a travel layover better, right?
There is a now a good-size Dylan's Candy Bar right in the terminal at Detroit Metro Airport - if you're a traveler, be on the lookout for sugar central. They sell classic candy by the half pound, more gummy products than you can imagine and they have a display wall of chocolate-covered everything.
The store also stocks a variety of their brightly colored branded merchandise like iPhone cases, tote bags and miscellany to show you "were there."
Swedish Fish, anyone?
