Taco's Mexican Grille -- Braselton, GA (I-85)
One of the developments in the Southeast over the last few years is the mushrooming of mexican hole in the wall restaurants in places where you might never expect to find them. This one -- at exit 126 off of I-85 -- is in one of the most surprising places of all -- 2 blocks from the interchange which serves the Chateau Elan winery/spa/ritzy etc facility. Given its location, this is a great place for I-85 travelers who (i) do not want to deal with finding good eats in Atlanta's sprawl or (ii) folks leaving Atlanta who want to clear Atlanta traffic before looking for lunch (or dinner).
This is authentic Mexican -- they serve the basic taco, enchilada, quesadillas with a minimum of fuss. My wife and I had the barbecued meat tacos (very good) and quesadillas. The Quesadillas were exceptional comfort food -- the taste very defined (rather than the blurry,cheezy bland of tex mex). We'll stop in again the next time we have to go out I-85.
Taco's is not well advertised from the interstate but it is easy to find. Drive south on Ga 211 (away from chateau elan). The restaurant is in the strip mall on the left just past the first traffic light.
