I have been to dive bars on three continents. This one is something special.
Cozy basement space lit with red and amber lights, a few blocks behind the Tulsa County Courthouse, next to a 24 hour bail bondsman. Friendly bartender, cheap drinks with some decent middle shelf whiskies and a good range of beers. Broad spectrum of working class folks of all ages and races, and (somewhat rare for Tulsa dive bars), it's non-smoking.
Add in the best house / chillout Spotify playlist I've heard in a long time, and I will most likely raise my double Tullamore (neat, in a rocks glass) in salute, and leave a favorable, if boozy, 5 star review.
