Twisted Tuesdays at the "World Famous" Inwood Tavern every Tuesday night from 9pm-1am. Drink specials include $3 house / $6 Top-Shelf Margaritas, $3 Blue Kamizazes and $4 wells. The drinks are very generously poured and the bar has a cool stage to sing on. They also have shuffleboard, billiards, a nice patio with fans and misters, and TVs all around the bar. There's free parking (although limited) out front, and a bigger free lot behind the bar. There's also a valet option available.
A really fun place to come out and sing on a Tuesday night!
