I did one of the ones in Moscow (near or on the Arbut?) several years ago. We didn't really plan to go, but our regular plans fell through.
I was there in January, at a time few tourists are in town, and the amount available of fresh food is limited. It was actually kind of nice to get a taste of home (and decent restrooms)! I did a milkshake, fries, and bacon double cheeseburger. The bacon turned out to be what they call "canadian bacon" here and put on the Egg McMuffins, really a round piece of ham.
Incidentally--the McDonalds in Sedona, Arizona, just north of here is the only one in the world with teal arches. Zoning wins a small victory!
