Hey, Ms. kitten. I saw your thread on Site Talk and thought I'd respond.
Have you tried Kiev Foods? From the Yelp entry by Elise S., "When they're in stock, pick up some Georgian kupati - a garlic-laden lamb and pork sausage with cilantro - that are made in New York. "
Who knows. Invoking the Y site might get this yanked, but I thought I'd try to help.
Moscow on the Hill used to have one dish - Lule Kebab - that I vaguely remember as being Georgian. Not sure, though, and I can't get their web site to show me the current menu, so I don't know if they still offer this dish.
(Travel tip: if you ever get to Chicago, search the boards for info on the Georgian bakery on Devon. Mmmmmmm!)
