Mrs. Doohickie and I have recently discovered Yucatan Taco Stand at 909 West Magnolia in Fort Worth.
I really like this place but...
It is noisy and it isn't cheap.
You don't get ripped off and there are definitely some bargains on the menu, but this isn't Taco Bell. I wish the noise level was a little less. This tends to be a place where it's hard to have a quiet conversation because you find yourself talking over the din. There, now that we've got that out of the way, let's enjoy ourselves.
There's nothing to be done about the noise (which actually is a problem at many restaurants these days). As for the price, the ambiance is upscale and the food is very fresh and high quality, and you pay for it; it's as simple as that.
Upon entering you go to a counter to place your order, get your drinks, and then you sit where you want. There is a bar area, a dining room and outdoor seating. All the areas inside are non-smoking, which is nice for this non-smoker. Once your food is ready they bring it out to your table.
Mrs. Doohickie is a vegetarian, and there are enough veggie selections to keep her happy. This visit she had the Latin Vegetarian Mix-Mex Grill
...and I had a Tempura Fish Taco and a Special Ground Sirloin Taco. Each was a handful!
I wouldn't quite use the word gourmet, but this food is very good, very fresh, well-prepared and well-seasoned. If you know to expect to pay a little more than you would for Taco Bell, and that people like to talk in here, you'll enjoy your visit.
