Buckey's has the best rootbeer on the planet.
@taramay: Even though I'm a frequent customer and fan numero uno of everything Buc-ee's, I'm gonna have to disagree with his one. A&W is number one, and Dog-n-Suds is a close second.
Edited to add: I only use root beer for ice cream floats...I don't really drink it straight, so this may skew my results a bit.
