Though this venue opened just last year, the place has already earned quite a reputation as one of most happening bars in the county. Located in the Artists Village of up-and-coming Santa Ana, Proof caters not only to the county's hipsters, but also to the plain ol' cats as well. Depending on the night, you can hear any of a variety of musical flavors being spun by featured DJs. While getting your groove on to those rockin' tunes and sipping your vodka tonic, you might as well ogle the bare-breasted artwork that adorns the otherwise-spare, industrial-looking walls. Don't fret, gals, there's something for you there, too—the ladies' room proudly displays pictures of male packages tightly wrapped in denim. Whew! Is it getting hot in here, or is it just us? Good thing you can head out to the brickwork back patio to chill out.
