We hesitate to point this out because Desperados, the longtime Tex-Mex hideaway on Upper Greenville Avenue, is one of our favorite weekend haunts. We hesitate because part of the reason we love it so much is that it never seems too crowded. Sure, it gets full, but it's not like one of those trendy Dallas spots where you know you'll wait an hour and a half every Friday evening. You may have trouble parking, as the lot is fairly small, but after that it's smooth sailing. The service is fantastic, the food is top-notch (everything from the "awesome nachos" to the puffy, crunchy Desperado tacos to the more expensive specialty dinners is worth putting in your mouth) and the desserts are sumptuous (the flan is worth the trip). Top-shelf 'ritas ain't too shabby, either. Desperados has fine North Dallas and Garland locations as well, but if you want to stay close to the Friday-night action without too much hassle, start your weekend here.
