The small Texas chain got started in College Station years ago and has spread to Dallas, Austin, and Houston. They serve up perhaps the best burritos I've ever had. These guys were around long before Chipotle and they are much better. They have lots of choices (4 different kinds of tortillas, 3 kinds of beans, etc) and better tasting ingredients. I've been a loyal customer since attending school at Texas A&M in College Station several years back and am thrilled that they now have a location here in Dallas right off Greenville (there's also one in Addison if that's more convenient). If it's your first time, get a "regular" and just go through the line (like you would at Subway) and choose your ingredients. I highly recommend the BBQ sauce! It's hard to say whether this really qualifies as Mexican food, as the Freebirds burrito really doesn't compare to anything you'd ever order at the standard Mexican restaurant. Even if you're not a big fan of Mexican food, you might want to give Freebirds a shot (yes, it's that good).
