Internet giant Google shelled out some $151 million to acquire venerable restaurant rater  Zagat Survey this past fall. The deal brought Google a whole slew of reviews and other handy dining information for its users’ daily searches. Ah, but, what to do with all those antiquated skinny red guidebooks? How bout a fire sale? Over the weekend, Google was hawking copies of the latest Zagat 2012 Washington/Baltimore restaurant guide for the low, low price of $7 a pop—-an advertised 54 percent off the cover price. (Limit 10 per person.) Google has said it intends to keep publishing the guidebooks. For now. But, with rock-bottom prices like this, you’ve got to wonder how long the online company’s commitment to print will last.
