B's Tacos is Tex-Mex done as well as anywhere in Texas itself, with overstuffed tacos and burritos served by the plateful to hungry Londonderry residents dreaming of warmer climates and southern twangs. But as authentic as the flavors are, the real standouts on this truck are the specials - loaded buffalo chicken burritos, spicy chipotle angus steak with fried potato, and chicken BLT burritos are just a few of the mouth-watering delights that shoot out the window daily. All ingredients are freshly prepared daily, and everything is made to order - so order what you like, cause you can't be steered wrong. It's enough to give you state-confusion, if only for one glorious meal. Chances are it's a confusion you'll be wanting to feel often.
