Practically an institution when it comes to tried and true taco trucks, Tacos Tierra Caliente, located at the corner of the West Alabama Ice House, may not be anything fancy, but it sure knows how to serve up tasty, inexpensive and authentic Mexican-style street tacos. Ringing in at $1.50 to $2 each, the lengua is juicy, the barbacoa moist and delicious, and the pastor is packed with flavor. Tacos come with a liberal sprinkling of chopped onions and cilantro. Add a squeeze of lime, top it with your choice of red or green salsa, and as they say in Mexico, "Provecho!"
