From Corey and Bob...
"The House of Tilden, downtown on Liberty Avenue, is the city's
only private after-hours club (frequented mostly by men).
Although membership is required, it is easily obtained. The main draw
of the Tilden is that it remains open until 3:30 am, although they stop
serving alcohol at 3. The Tilden also has a small dance floor. Since
the Tilden has no external markings, have a friend help you find it."
