Does McDonald's sell more burgers than any other restaurant chain in the world?

yah, it is....there's like over 3 billion in the world today. That's what I learned in Health class at least. ---> actually this is 100% wrong ther is nothing close to 3 billion mccdonalds so you might want tell your health teacher he is wrong. The largest fast food resteraunt chain is subway with an average of 34,000 resteraunts and mccdonalds has 32,000.
