When it comes to fajitas, the choices in Houston are abundant, but at the end of the day, the all-time winner for consistency and plain old deliciousness all around is, and always will be, The Original Ninfa's on Navigation. It's the reason why, at any given moment, Mama Ninfa's original location continues to bustle and thrive. Chef Alex Padilla does a great job making sure that each sizzling plate comes out perfect. The Hereford outside skirt steak is tender and tasty. Combine this with caramelized onions and your choice of guacamole, sour cream, cheese, pico de gallo, and charro or refried beans, and what you have are fajitas as they were meant to be eaten, old school and without question fantastic.
