I've also done an extensive search. To my knowledge, nothing exists. I photographed their menus during my last visit. Not sure if it has since drastically changed, but hope it helps. The link can be found in the following post: http://chowhound.chow.com/topics/563398
As far as I know they do not have a website, but when I was going there to dine with a friend that is blind, they faxed the menu to me, so we could review it prior to arriving. It saves me from reading it word for word to him at the establishment.
