Fast food has come a long way over time. McDonald’s (NYSE: MCD) reigned supreme over its chain competitors throughout much of the second half of the 20th century, distinguishing itself from both its fast-food peers and its slower casual-dining counterparts. But in the 21st century, fast-casual giant Chipotle Mexican Grill (NYSE: CMG) led the way in producing a new way for people to eat. Investors looking for stocks in the consumer space are curious whether Chipotle or McDonald’s is a better bet right now.
