SILVER LAKE. Half Indian restaurant, half bar and dance floor, Tantra provides an evening’s worth of activities under one roof. Once a theater, the large bar area now plays to patrons with concoctions like the exotically-named Tears of Ganesha and Pinilla Dream. Adding to the Eastern ambience are Bollywood movies broadcast on plasma TVs scattered throughout the space and an in-house DJ spinning soothing house music, encouraging you to lounge and dance, alternately. Tempting, savory Indian dishes are served in the restaurant until 11pm and midnight on the weekends.
