Probably the new Festival Center with the rumored "rooftop bar." At least it looks lush and not generic or sterile.
Also, with credit to the Magic forums, here are the posters hanging up in the Epcot area at D23...
I both love these and find them distasteful. The retro style applied throughout, complete with vibrant colors, is GORGEOUS. They push a lot of nostalgic buttons even for the "modern" attractions. I'd buy a set of prints immediately if they were offered.
But it's also so transparently dishonest. Disney's trying to say, "See, everything fits together! It all belongs in Epcot!" Nah.
