Entered Trio's somewhat skeptical as I waited on food from Thai Kitchen down the street, and left a fan. I give Trio's a 4/5 not on the same scale as a place like Velvet Tango Room (5/5), but on its own dive-bar metric. Went during happy hour with a group of 6, and our tab came out to less than $15... though, the utterly inebriated bar tender might have miscalculated. I forget her name, but she was quite friendly despite being as sloshed as a Brown's fan in November and we felt welcome immediately. The gin and tonic was perhaps the worst I've ever had, but that only added to Trio's dive-bar charm. (Get beers on draft)
Yelp often mis-labels establishments as "dive bars", but Trio's definitely earns it. I am coming back.
