This is such a fun activity - and a tradition with my College Program roommates every time we head back to Disney for a reunion.
We always start in Mexico with the fiesta Margarita and proceed as follows:
Norway: Carlsberg
China: Tsing Tao or Plum Wine (plus an eggroll)
Germany: Beer or wine (along with a bratwurst from Sommerfest - yum)
Italy: Rosa Regale or Prosecco
USA: Sam Adams (and sometimes a funnel cake or cheese fries - or both)
Japan: Sake
Morocco: Marrakash Express
France: Grand Marnier slushie (with a pastry or crepe!)
UK: We used to always do the Welsh Dragon, but this last time had a drink with Bailey's, Amaretto, Kaluha and a splash of Coke - with was Amazing!
Canada: Beer
The key is to make sure you eat as you go along, so you can make it all the way around without falling over.
Have fun everyone!
