I don't know why Gastonia has so many "sit and be waited on" LatAm restaurants, and just a few humble tacquerias. I agree with other reviewers, if you're looking for a place like this, it'll meet your expectations. You can get some genuine items inexpensively and they have a modest menu that goes beyond the usual tacos and burritos.
The ambiance of being in the back of a long building, with no windows, makes it feel a bit hole-in-the-wall ... but the seats and tables are tidy. If you're an anglo the staff will speak to you in English first. As a humble family kitchen, it serves it's niche here just fine.
