If you are in New York, Los Angeles, San Francisco, or Chicago, you can get a report every week on where the free booze is. Or free music, or whatever. MyOpenBar.com will send you a newsletter, or you can check their site anytime you need a really cheap date idea. For example, tonight The Blue Owl in the East Village will have complimentary gin from 5-6 PM to unveil their new cocktail menu. Other events may require reservations or invitations. They plan to expand to other cities soon.

(Thanks, Jan!)
