The new Mcdonalds food/beverage stand is now open in Epcot. It's located between Canada and the International Gateway entrance to World Showcase. As you can see from the link below(from WDWMagic.com under the August 8th update), there are no golden arches visible anywhere. Many guests here feared that the new food stand would stick out like a sore thumb, but as you can see the building is pretty non-descript and generic looking.
