I have one about 2 minutes from my home, and I eat there maybe two times a year.
Their food definitely isn't bad, and you might even say that it's good.
Ironically, just last night, I was hanging out with my ex and our three children. Our one daughter was telling us about a dream she had in which all sorts of things went wrong when she was just trying to eat a taco. She then couldn't get tacos out of her mind, and we went out for tacos last night. I thought that we were going to Taco Bell, but they insisted on a Mexican restaurant. When we got there, I honestly didn't like how their tacos looked, so I ordered some empanadas with a side of rice and beans. My ex and our children all had the tacos, and then they all complained that they didn't like them.
We should have just gone to Taco Bell. Again, nothing overly fancy, but their tacos at least taste good, and they're reasonably priced. I'd say give it a try. Everyone has their own tastes, but I don't think that you'll hate it there.
