The food is significant and cheap. My first time involved a $2 taco and a $5 burrito, and it was far too much for for my lunch. This last time was a taco and a basket of sesame fries ($3). Good, basic stuff. Nicely crunchy veggies on top. The fries had a rather strong after-taste, though…
Why only three of five? Hm. Neither time were my taste buds rocked the way I expected and wanted. And they tend to run out of items quickly. At first, I figured that was just because they weren't sure of the demand. They've been around long enough and gone to enough events that they should have a better handle on their ingredient quantities.
That said, if they were near my building at Georgia Tech, I'd likely hit them up for a few tacos pretty often.
