There's something floating around Austin right now called the Dewhurst Bill that'd make every restaurant in the state BYO wine -- but if legislative proposals this awesome actually had a chance of becoming law, wouldn't this email be in Esperanto? So in the meantime, GoBYO.com.
An easily searchable and diligently updated database of DFW eateries covering all levels of sanctioned wine-smuggling, GoBYO was launched by QVC's co-founder and his granddaughter, who clearly want people to drink more of the stuff that makes them buy things off QVC. Plug in your zip, and you'll find a liver-pleasing spread of restos that charge no corkage fee at all, such as City Cafe near Inwood Village, Lower Greenville's Sevan G&G Cafe, Balls Hamburgers' new NW Hwy digs, and Uptown's P.D. Johnson's Dog Day Deli -- a business P.D. started after his t-shirt idea was stolen by his brother, Big. Spots that do charge corkage can be surprising: S&D Oyster Company ($2.50 a head), Fadi's ($1 a glass, so top it up), and Mattito's Tex-Mex ($5 a bottle), on up to Sambuca -- where even with the $20-per-bottle tariff, you could still save enough to become a lamb meat-baller.
If you've got more specific needs than "drink cheaply", narrow things down with 40 search terms, including cuisine, live music, karaoke, pet-friendliness, even baby chair availability, so that as you quaff, you can sit your newborn at the table and instrui li Esperanto do li poto paroli kun William Shatner.
