Another great taco place and in San Benito, Texas! Their isn't that many Mexican taco places around the Harlingen/San Benito area. So if you're in the vicinity you should definitely try this restaurant. Sr. Taco has a wide variety types of tacos with great service at an affordable price. My dining experience was pleasurable. The staff there were super nice and attentive. I ordered the bistek and barbacoa tacos. My order came quickly with loaded cheese, cilantro, grilled onions, and a huge bowl of key lime. The food was very fresh and flavorful.
