The trays on the waitresses’ arms at Buttons Jazz Café in Desoto are filled with neon blue and red cocktails as they pass through a crowd of well-dressed patrons on a Thursday night. While the dinner rush has come and gone, there are still food orders being placed in front of patrons, but everyone is there for one reason. A popular jazz band performs on the high stage that sits on the back wall directly behind the bar. And though the place is set up like a proper chain restaurant (there are other Buttons locations in Fort Worth and Addison), it doesn’t stop people from scooting the tables out of the way so they can cut a rug.
