Smartly dressed guests gathered at Herald Square's gorgeous Gotham Hall last night to commemorate the 30th anniversary of HIV/AIDS prevention, care and advocacy non-profit Gay Men's Health Crisis. Weeds star Mary Louise Parker served as the evenings emcee, which also honored Tim Sweeney, the Rudin family, and pharmacy chain Duane Reade. Guests including B.D. Wong, former NYC mayor David Dinkins, and Issac Mizrahi were treated to dinner, a live auction, and the musical stylings of performer T. Oliver Reid. Duane Reade is also the sponser of this year's upcoming AIDS Walk New York which raises funds to support the services provided by GMHC and other AIDS service organizations in the tri-state area.
