One of those Marigny hangs that's as much neighborhood dive as gay bar, Big Daddy's held down its corner long before the word gentrification was whispered around here. During the day and early evening, it's a joint for regulars; late at night, party people, scenesters and service-industry workers flock here. Open 24 hours daily. No food. Happy hour 4 p.m.-8 p.m. and 4 a.m.-8 a.m. daily.
