I asked them this question a few days ago and they said they do not. However, they do ask that men do not wear tank tops. I'd recommend at least business casual judging by the atmosphere of the place.
My fiancee and I dined there in Feb. and she wore a dress while I chose not to, but I did wear a sport coat, plus there were those in much more casual attire.
I agree with Christopher Bross. I checked on it too. Most there seemed to be wearing business casual.
