The Aggie Lounge, better known to locals and regulars as "The Lou" is the closest thing you'll find in Manhattan to a dive bar. This place opened in 1952 and has been rockin' ever since although I don't think they've updated any of their decorations since day 1.
If you didn't know this place was here you'd probably never think it was a bar. There are no windows and it occupies a space that's roughly 10x30. There is a jukebox up front with a stellar collection of Outlaw Country and 70's rock. If you play anything else you may be asked to leave. David Allan Coe is always a safe play at The Lou.
Originally they only served draft beer but over the last few years under new ownership they've added a full bar. You can also get a bag of chips or try a pickled egg which is a tradition of first timers.
The Aggie Lounge is not a great place for a quiet date or a romantic evening on the town but if you're looking to get away from the typical college bars in Aggieville and wanting an ice cold beer and a game of darts this is the place to go.
