I called the Twentieth Century Club today (February 19, 2010) and they informed me that you "absolutely" need to know a Member in order to be sponsored to have a wedding reception at their facility. The Club does not facilitate sponsorship in any way. Once you found a Member (on your own) willing to sponsor you, you can call to speak with the Manager to set up your wedding date.
Steel from Buffalo Rising posted a story yesterday on the 20th Century Club, its history and architecture. I’ve heard great things about having wedding receptions there from many forums, as I discussed in a past post. Next time I'm in Buffalo I will definitely have to check it out!
It’s such a beautiful place!
