Nathan Hill and Denis O’Donnell’s honky-tonk furthered the Eastside music expansion when it opened on Comal in Dec. 2011.

Sundays long belong to Eastside institution Conjunto Los Pinkys. The low-set stage and oft-packed crowd filled with dancers from seemingly every generation alive often makes it tough on busy nights to see the singer, but even from the cheap seats it can be obvious that visitors to the Horse have tapped into Austin’s age-old ethos.
