Buy the bar. No joke, this is how you turn bartending into a career. I have friends that did it from bartender -> manager -> owner, all at the same dive.

Oh, and you want it to be a dive bar. Or craft beer. Food is a pain in the ass, fancy cocktail bars are hyper competitive and not always profitable.

Dives get the best crowds/most dedicated regulars, and you can make a mint with high-turnover beer/shot specials.

And make sure to install a pinball machine.
