Ninfa Laurenzo is the mother of a small empire of Tex-Mex restaurants, and years later the Ninfa's on Navigation is the crown jewel of all the places that carry her name. It all has to do with the quality of the beef fajitas, and there is no substitute for the tasty Hereford outside skirt steak. Chef Alex Padilla marinates the meat simply with soy, salt and pepper, then throws it on the grill for that perfect char. The fajitas are served on a classic sizzling plate over naturally sweet caramelized onions with a small side dish of grilled peppers, and the thing to do is to grab a hand-made flour tortilla and fill it to the brim with refried beans, pico de gallo, guacamole and sour cream, then top it off with the onions, peppers and thick cuts of meat. Now, take a bite. This is what fajitas should taste like.
