It’s easy to remember what street La Calle Doce is on in Oak Cliff — if you speak Spanish. It’s been on 12th Street (“calle doce,” natch) for a long time … in fact, 30 years. On Wednesday, Dallas County Commissioner Dr. Elba Garcia and others will join owner and founder Laura Sanchez to celebrate three decades, with complimentary margaritas, beer, wine and appetizers from 6 to 9 p.m. La Calle Doce is also offering $3 house margaritas all week at both the original location and the Lakewood location on Skillman.
