If you live in Southern California, you have the chance to hear a superb singer and comedienne, Shelly Goldstein, who describes herself as "a gay man trapped inside the body of a straight girl." She's performing this Wednesday and the two Wednesdays that follow at the Gardenia, up on Santa Monica Boulevard, just on the outskirts of Hollywood. The Gardenia is an intimate supper club with pretty good food and, at times, wonderful entertainment. Shelly is providing three of those times this month. For reservations, dial (323) 467-7444.
