The biggest rival of Starbucks, which has opened 3000 stores in five years, is McDonald's?

McDonald's officially declared war in 2008, putting a provocative slogan in front of Starbucks' Seattle headquarters for $4 was foolish, which seemed to resonate with passers-by who questioned the high price of Starbucks. According to the Los Angeles Times at the time, McDonald's spent $100 million on McCoffee, launching its biggest business since the 1970s.
