I live in Mexico where there are a fair number of McDonalds. In my experience, they are not economically friendly and much more expensive than in US and Canada.
On another note:
Did you know that the McRib is processed with 70 different ingredients which include azodicarbonamide, a flour-bleaching agent often used in producing foamed plastics? McRib's are basically "restructured meat technology" containing a mixture of tripe, heart, and scalded stomach. Proteins are extracted from this muscle mixture and they bind the pork trimmings together so they can be molded in a factory. The McRib is really just a molded blob of restructured meat, advertised and sold like fresh ribs. There's nothing real about it, the preparation or the substance. In fact, McRibs really came about because of a chicken shortage. The restructured meat technology approach kept the McRib on the menu, despite the shortage, and the profits continued rolling in
Sounds really yummy, doesn´t it?
