I never heard about the limit of foreign restaurants. Fast food chains like McDonalds are absolutely everywhere. The food there however is significantly better than in the US.
Definitely. In the US there are countless better alternative fast food options to McDonald's, so it's a lower class / lower middle class targeted chain. In the US McDonald's competes on price to stay in that budget range rather than trying to move upstream on price. McDonald's is to fast food in the US what dollar stores are to retail.
In foreign countries the financial targeting is different and there are always fewer McDonald's per capita. There are twice as many McDonald's per capita in the US vs France for example (and France has a lot of them at nearly 1,500); Britain has a similar ratio as France.
