Is it? According to Imagineer Zach Riddley, it's a dining experience that "builds upon our World Celebration story by focusing on connections that generations of people make while gathering over a meal", featuring the "relationship of place, people and food from across the world – celebrating the bountiful variety of ingredients and traditions that connect culture and food to the beautiful, diverse places that we call home", with "unique design features that echo EPCOT of the past that are just stunning".
A place where "the gardens and greenery within World Celebration will complement the interiors, allowing our guests to harmonize with nature outside; how friends and family will gather together around a meal or beverage; and how show kitchens will provide a culinary experience for our guests within. The kitchen you see represented here will actually be responsible for making a variety of baked goods, which will be available at Connections Eatery".
And a hub that encourages “connecting”– by the common bond we share over food and the gathering of people across cultures. EPCOT is a park about people, and this new location within World Celebration will commemorate that with the talent and skill found within the kitchen, and those who gather together to enjoy each other’s company over a meal".
. . . That or they were BS'ing us. Shocking.
The fact that it's merely a burger joint being talked up like a meaningful addition is, like, the problem.
And not for nothing, but nowhere in any of the copy about this restaurant (and boy has there been plenty) is any reference made to the World's Fair concept at all. Insufficient though an attempt at "theming" that would be. So I think you're either giving them a freebie on that or your making things up to suit your opinion.
Once again, "there's no there there" in Connections Cafe.
