I found this today on DonRockwell.com. There's a sparkling wine dinner at Komi, December 19th with Champagne and sparkling wine pairing by Komi's new Sommelier, Adam Curling. If you've been to Komi before, you know the is sure to be a fun event and will be well worth the money. If you haven't been yet, then this will probably be a great time to try Komi for the first time.

Call (202) 332-9200 for reservations.
$150 per person. (Ask about gratuity, I don't know.)

P.S. I'd make a reservation soon because there's already 1 less table available.
