I'm surprised that I have not seem this Taco/Mexican food cart mentioned before. Maybe they are new (I have not asked the owner when they opened). La Yucateca Tacos Y Tortas is located on the NE corner of Starkey Rd. just north of Ulmerton (across the street from Anheuser busch dist.).
Anyhow, I've only been there twice - having pork tacos the first time and a burrito the second. I highly recommend both. The pork was wonderfully marinated and absolutely delicious - served on the best tortillas I have had in the Clearwater area. The chicken burrito was great. Incredibly tasty w/ fresh ingredients. Their homemade hot sauce has a great taste and a perfect heat level for me.
If notice their cart on the side of the road then stop - I think you will be happy that you did.
