Update: Zagat claims the number of cities available will be expanded to 50 over "the coming months," and that old restaurant reviews will be made available on the web page "soon." Woohoo, a whole 50, guys!
Ever have your parents pull the old 'bait and switch' on you when you were a kid? "Hey Jimmy, here's a brand-new bike. And by the way, your mom and I are getting divorced!" Well, Google pretty much just tried doing basically that to Zagat fans.
