A Sunday afternoon at The Grapevine is like a celebration of population density. It's a shoulder-to-shoulder mob, every member of which is either swaddled in post-brunch bliss or has just woken up and is making a breakfast of Velvet Hammer or Everclear bellinis. While drinking in general is skill that needs constant honing, day drinking is something more. It's an art. A craft even. And bars built to encourage day drinking are workshops where practitioners can perfect their craft. On any given night Grapevine pulls in a crowd that's big and always diverse, covering a mélange of sexualities and a healthy mix of ages. It's part of what makes the place so appealing, that it communicates a sense of weirdness and welcoming at the same time. And that's what draws the crowd every Sunday. That and the chance to suck down bellinis while soaking in vitamin D.
