Well, Dallas finally got The Bird. First it was College Station (in 1990), then Austin (in 1999) and Houston (in 2001), but it seemed Big D might get lost in the shuffle. So when Freebirds World Burrito opened this spring in the Old Town shopping center, the lines that formed outside made it clear that this grand opening was a long time coming. Freebirds makes the best burrito this side of the border, any border, ever. But the customer has a lot to do with that, considering all the options The Bird offers for its burritos. Sizes range from a half to a super monster, and there are four types of tortillas, six kinds of sauces and ingredients too numerous to mention. Let's just say there's a bunch of 'em, and they're mighty tasty. If you opt for the monster or super monster, though, be prepared for leftovers.
