Eater Houston: 15 Essential Tex-Mex Restaurants In HoustonGringo’s features around a dozen locations across the Houston area, but if you’re interested in seeing where it all began, head to the original in Pearland. Each outpost showcases Old West meets Mexican art and antiques while delivering Tex-Mex favorites like taquitos, grilled seafood, and some of the best fajitas and margaritas Houston has to offer. If you’re feeling festive, try the star-spangled banner, a combination of strawberry and lime margarita, swirled with blue curacao. End your visit with complimentary soft-serve ice cream.
