Taqueria la Esquina has recently opened shop in the deli at the Exxon station located at 10500 Chapel Hill Rd, Morrisville. Its got a brief and standard taqueria menu - tacos, quesadillas, tortas, burritos, etc. They have some breakfast options in the form of various breakfast sandwiches/wraps/biscuits and a few gringo style deli sandwiches like tuna salad and philly cheese steak at lunch.
This place is close to my office, so I grabbed an order of tacos (al pastor and pollo azado) to go at lunch time today. The food was just fine, but not nearly as good as Taqueria Rancho Grande in Cary or La Vaquita in Durham. Still, its nice to have this quick and inexpensive option nearby for the next time a taco craving stikes at lunch time.
