Mama Margie's is “nacho” ordinary fast food late night Tex-Mex joint. They've had several locations in San Antonio for quite a few years, but I never paid them any attention until recently. Why, why, oh why have I overlooked this inexpensive late-night Tex-Mex destination for so many years?They're open 24 hours a day, so they're always available for your late-night snacks, early morning breakfast, lunch, and dinner.The beef fajita nachos are out of this world. Tender, flavorful fajita meat on top of a nice layer of cheese and refried beans on fresh, crisp tortilla chips. A hefty scoop of guac and sour cream is included in the middle of the plate.I'll be honest though, the seating kinda sucks and sometimes you have to sit at a table near the ordering area which can be annoying. Everyone backs up to your table while you are trying to eat and hang out.They don't have the best salsa bar in town, but it holds up fairly well. Unlimited (free) chips, several varieties of salsa, and free jalapeno slices for your nachos.Ice cold beer and good margaritas for sure. I stake my reputation on that one.
