We went on Sunday and it was enjoyable. I expected the lines to be longer, especially since a CM said they would be. Fortunately, that wasn't the case. I liked the atmosphere and the small portions, you can try a lot of different foods without feeling
Some suggestions:
Take cash. Many of the handheld devices weren't working, some guests couldn't use their credit cards. There was lady in front of me that had to walk away because they couldn't get the device to work.
This event is best enjoyed without children, IMO. If your children are adventurous eaters, they would probably enjoy it. My kids are not. My DD had some creme brulee and the beef dish from Argentina. My 14 yr. old had pizza from Italy. My 11 yr. old didn't care for any of it.
Foods we ate:
France~ Chocolate Creme Brulee, very good.
USA~
Spareribs and corn. Don't waste your money and time. It was the worst, IMO. The smallest portion of all the things we tried.
Italy~ Pizza, nothing special.
Mexico~ Chilaquiles, very good.

The chicken and chorizo quesadillas also looked very good, I wish I had tried them. This is coming from a person that isn't a fan of Mexican food.
Argentina~ Grilled Sirloin with Chimichurri sauce. Very good meat and potatoes, too much olive oil in the sauce. I still recommend it.
Spain~ We wanted to try the chorizo and potatoes. I noticed a family eating it and asked for their opinion. I didn't even get to finish my question

, they said it was a big disappointment and tasted nothing like real Spanish chorizo. So, we skipped it!
We don't drink, so I can't tell you about the liquor. However, I have a somewhat funny story... There was a young guy (20's) that obviously had a little too much to drink and he was talking very loudly on his cell phone. He said," Yeah, I'm here in Epcot...
in Tampa".

He actually paused to think about it before he said it.
ETA~ The kiosks that we visited all used the same system. You order and pay at the first booth, they gave us the laminated cards that specified the foods that we ordered, then we presented those to the CMs actually serving the food. It's a pretty good system, no problems at all.
