I’m sitting in the basement of a Mexican restaurant. Upstairs, the rumble of families munching on enchiladas smothered in refried beans and sipping head-sized margaritas under red neon lights is only slightly audible. A door at the top of the wooden stairs closes, and a crowd of mostly gay men and their girlfriends sits in this underground theater. I’m completely in love with this so-not-typical Los Angeles vibe. Cosmos are replaced by Coronas, and the unpretentious crowd sits quietly for a performance at the Cavern Club Theater (920 Hyperion Ave. Tel: 323-662-4255. www.cavernclubtheater.com) below the family-owned Casita del Campo restaurant. The wood beams creak above with the movement of the upstairs patrons as the show, Little House on the Prairie-Oke (or after the threat of a lawsuit Almond Grove! That Pioneer Karaoke Musical Formerly Known as Something Else), begins with an Ingalls breakdown dance. The crowd expresses sheer joy at the ridiculousness of the entire situation. When Drew Droedge, most famous for impersonating Chloë Sevigny on YouTube, takes the stage as the obnoxiously over-the-top Nellie Oleson my face beams as red as the lights upstairs. He must have noticed just how much I was enjoying it, because he pulls me on stage for a finale dance party. When the show closes, the cast eagerly meets the audience over beers, and I’m floored by this sliver of underground gay culture.
