$YUM disappoints, and China problems get the blame. But have you been to a Taco Bell lately? I used to love Taco Bell, but I rarely go anymore. Instead, I find myself at Chipotle Mexican Grill (CMG) or Dos Coyotes, or even a local Mexican restaurant. I just don't like the fast food Mexican stuff like I used to - or, maybe the quality of the product is down and there are better alternatives.
I also think KFC is getting more competition via chicken wing outlets, too.
