Maybe... but not very much, unless it applies to the food. Our local McD's actually just rebuilt their store, so ask me again in a couple of weeks and I might have a better idea. And I mean rebuilt, not remodeled... they tore the building down and totally rebuilt it.
The McDonald's closest to where I work could use a makeover. The interior is vintage 1990s, maybe even late 80s. It's in really bad shape. However, they mention modernizing the interiors like Starbucks and other cafés. Eh, no thanks. I don't hang out at Starbucks because I find their seating uncomfortable. It might look interesting and contemporary, but I prefer function over form.
