It's not too late to RSVP for the fabulous fun-filled Fat Tuesday extravaganza known as Mardi Grist NYC. Guaranteed to be the grooviest, greenest, grandest gig in town - the party hosted by our good friends at Grist Magazine is sure to blast your mid-winter blues into oblivion. Head over to the Mardi Grist site and give 'em your 411 so they can be sure to have plenty of treats and libations on hand. $20 in advance and $30 at the door. 6 - 9 at Gstaad in Chelsea.
