Picholine, the Upper West Side French-Med that ranks in several Zagat Survey Top Lists (Food, Most Popular, Service, Private Rooms and Mediterranean Food), is celebrating 15 years. And for its 15th birthday, it wants to give you a present: a $50 gift certificate redeemable throughout 2009. Just head to www.picholinenyc.com, scroll down the page and click on the "Complimentary 15th Anniversary Gift Card" icon in the lower-left-hand column. Fill out your information and the gift certificate will be mailed to you shortly. The five minutes that it will take you to sign up will get you more than half-off the restaurant's four-course prix fixe ($98). Happy birthday!
