The Audrey bar inside the W Tuscany Hotel was closed last night for a GALA mixer. Ivies downed complimentary Svedka cocktails from 5:30 to 7:30. The crowd was typical ivy-gay: older lezzies talking shop and gray-haired daddies eyeballing the spry young dandies fresh from a day at the firm or bank. Asians, both male and female, abounded and saphic lovers were plentiful, more butches than lipstick ladies. On the boy front, a few typical, preppy-cute guys save for one just-graduated, dropdead hunk with many fans fawning outside. At least there was free booze.
