If you're hunting for this divers unmarked location within the decidedly button-down south Mesa plaza that houses it, steer clear of the law firms, real estate companies, and other white-collar business and instead look for the Christmas lights on the roof of the Pub 'n' Grub that seemingly operate 24/7/365. And yes, the bar is most definitely open for business, despite its perpetually closed window blinds. The non-stop sounds of revelry generated by its rogue's gallery of regulars manages to leak out, however, from the cheers of the victorious players cleaning up on the two pool tables and the thrum of classic rock hits on the juke, to noisy debates between patrons at the cigarette burn-scarred blonde wood bar about whether KISS or Ozzy got more trim in the ’70s. Such discussions often occur over Pub 'n' Grub's American bar food standards, most involving chicken, and imbibing any of its 14 different drafts. The overall vibe isn't so far from 1984, the year the joint opened.
