This is really going to display my ignorance...
Have you guys ever heard of Root Beer? It's a carbonated soda beverage, like a cola drink but better *grin* I think it might also be known as Ginger Beer or Sasparilla (although Ginger Ale is something completely different). Some of the popular brands in the U.S. are A&W, Dad's, and Barques.
The reason I ask is because my son (7 as of last week) really loves it, but it's not to be found in Portugal. If any of you have heard of it, that at least gives me hope that I might be able to find it available elsewhere in Europe and order it in time for Christmas.
Thanks!
