A dollar doesn't buy what it used to do.
Earlier this week, Yum Brands' Taco Bell launched its new Dollar Cravings menu. Unlike many of its competitors, the items actually cost just a buck—rather than a buck and change.

"If you look at the economy today and how much pressure is on the consumer, I think value is at least as important as ever," said Taco Bell marketing chief Chris Brandt in a phone interview.
So what exactly can a dollar buy these days? CNBC called up numerous locations of fast-food outlets in the three largest metro areas (New York, Los Angeles and Chicago) to find out.
