Jared, that depends on what you want to drink in that country.
Let's see, beer right now, starting at international showcase turning right-
France. No good beer really. Bottled La Belle at stand. Wine by the glass in the bakery, and at stands. No reason to go to restaurant for beer they don't have anything else iirc.
Morocco. No good beer really. Bottled casablanca at stand. Mixed drinks at stand and at counter service restaurant, no need to go to mirrakesh restaurant.
Japan. Kirin Ichiban on tap in Tokyo dining is probably the most drinkable beer here. They have a full menu of drinks, some available at stand.
America. No good beer, really, sam adams at stand and at fast food. No sit down restaurant anyway.
During the food and wine festival, sam adams has a stand here that has a lot of their beer.
Italy, no good beer, wine readily available at outside stands along with whatever italian lager the distributors are pushing (Peroni?)
Germany. Germany is probably the only country where the beer choices have gotten better in the past 10 years or so. Three places to get beer here at outside stands - franziskaner at pretzel kart out front. Beer stand on the side with becks (? not trusting memory there). Spatinator and franziskaner at bratstand inside to the right of summerfest buffet. I want to say there is an octoberfest type of beer there, but that may be seasonal, maybe a food and wine festival thing, I haven't noticed. No reason to go to the buffet for a go-cup, but if you eat lunch there, it would be about time for lunch now, they have liter glasses in there.
The outpost has sam adams seasonal at the counter service.
China. Not much beer choices. they have tsingtao at the counter service, some drinks and wine also.
Norway. I still miss the ringness. they have carlsburg at the stand outside, some drinks and beer to go at the bakery also.
Mexico. The frozen margaritas at the stand aren't that good, imho. They have XX at the fast food place and temporary stand on tap. They have the tequila bar inside.
Canada. The only beer they have outside is moosehead lager and light on tap. Got to go to la cellier for the less skunky tasting beer. Probably the best beer available at epcot is the unibrou beers in la cellier, but here's the thing. If you've been going drinking around the world to this point you'll be perfectly happy with the moosehead and should stick with that instead of trying to go in and eat at the restaurant.
UK. They have bass on tap outside. Go inside for the guinness (it is too expensive at 8.50 a pint, so 10 bucks with tip, but so quinching on a hot day, and 10 bucks for a pint of guinness is better than 8 bucks for a pint of wife beater). Also boddington's and of course mixed drinks and ciders inside. I don't know why half the beer in the UK pub is from Ireland or Belgium, but wth.
The last couple of years there has also been another stand with some inbev beers (hoegarrden, etc.) during food and wine festival.
In future world, the ice cream stand behind character connection/innoventions, on the way to the land/nemo has sam adams seasonal on tap; there is stand on the other side towards test track with yeungling I think on tap.
