I once asked a man, "what is best in life?" He responded, "To crush your enemies, see them driven before you, and to eat their queso."
My days of crushing enemies are long behind me, but I will be a devout queso eater until the day I die (as if you couldn't tell from my nachoseries). A fair amount of restaurants in St. Louis serve queso, but only a few stand out to me. I think the Tilford's have a great one at Mission Taco Joint & Milagro, and the queso on Publico's arepa platter disappears as quickly as it arrives, but none have tickled me quite like Nachomama's.
Nachomama's is one of those places that isn't going to blow you away with their TexMex fare, though, to be fair, I don't think there are many places out there that will. It's good, though. A great place to go for a casual dinner with friends, especially when the weather is nice. Grab yourself a margarita, pick out your favorite TexMex fare, and be thankful that you're not stuck eating Chipotle or Crazy Bowls & Wraps again for the umpteenth time.
Their queso isn't complicated—it's a pretty standard take on queso blanco. Cheese, milk, light seasoning, and what look like some chopped jalapenos and tomatoes. It's mild, but perfectly mild. It pairs wonderfully with their salty tortilla chips (which you have to get a large order of, if only to have your food come in a flower pot). But the real joy comes from pouring the queso over everything else.
Tacos? Yep. Nachos? Extra cheese. Sometimes I'll even dip a quesadilla in it, which is a sure sign that I know what I'm doing, and that I'm fat.
Two other things to know about Nachomama's: their guacamole is very good, and their rotisserie chicken is actually the best thing on the menu. It's always juicy, and it's got a really nice spice to it. If you haven't tried it, you should. Right away. Go.
