Woot! My favorite type of pop got a shout out!
Ironically enough, some brands tout themselves as be 'Kansas City style', yet there isn't a single place in KC that makes or sells sarsaparilla (and hasn't been since the 1930s).
If you're ever in Wichita, KS, the Cow Town Museum actually makes their own sarsaparilla on site. You can also buy 1 liter bottles of sarsaparilla (Frostop brand) at any Atwoods. Leeker's Family Foods (at 61st and Broadway) sells Souix City brand. Does anyone else think it's weird that out of Arkansas, Kansas, Missouri, Nebraska, Oklahoma, and Texas; the only one of those states that has anywhere that sells sarsaparilla is Kansas?
BTW: If you like mixed-drinks, there is one for sarsaparilla called a 'Spaghetti Western'. It's a 1:1 mix of sarsaparilla and Root 100 (a 100 proof root beer flavored liqueur). It's usually half a shot glass of each.
