You Are What You Eat what you buy on Amazon

Howard Sherman points to a new Amazon service that lists menus, reviews and other information from eateries. He points out that the interesting part of the service is the

"ability to click on products and services bought on Amazon by people who also visited a particular restaurant's page. For example, if you're poking around the menu page for the pricey but wonderful Grammercy Tavern, you're also likely (according to Amazon at least) to have purchased a Britney Spears album or the book "Money Ball" by Michael Lewis.

Interesting, I've read Money Ball and eaten at GT.

Howard also notes that Jeff Jarvis thinks that by "the time this system is fully fine tuned, it will be a marketers dream."
