Well, who knew? Apparently there is a new boss in town, just ask McDonald's. McDonald's - and according to the ad for a "limited time" - is bringing the Swiss & Mushroom burger. There is so much hoopla about this McDonald's is plastering on every other billboard in town. The ad, interestingly, goes away from usually jovial McDonald's ads - in offers and new products - and goes towards black (probably to imply shady dealings or whatnot) which paradoxically makes it more noticeable but also less associated with McDonald's truth be told. Still, if you are a fan, and since is for a limited time, you know where to go.
