The food here was on point. The tacos are what they are (you know what you’re paying for), but compared to other locations I’ve frequented, this location’s tasted fresher and also didn’t skimp on the protein in the filling. The gentleman who helped me did forget my drink initially, but when I drove back around to the window I didn’t even need to say anything, he had it in hand already along with an apology, which is leaps and bounds better that what I’ve come to expect.

The customer service is great and it’s down the street from my job. Once in a while in a holiday or something I’ll stop by and make a big order to reward and feed my krew.
