Through some foodie groups I learned about a neat little pink trailer in far West Katy that serves cochinita pibil tacos and tortas.  

My torta was very tasty and very juicy and dripping.  The pork was very tender and a bit spicy with a bit of citrus.  It was served on hot pressed bread with avocado slices and pickled onions.

I just wish the location was a bit more convenient because I would definitely go more often if it were closer and easier to get to.
