It breaks my heart to give El Burro 2 stars, it would be 0 if it weren't for the kind girl behind the register running food and orders.
I was beyond excited to get vegan tacos, after all there was a separate vegan/vegetarian menu. I was eating my second vegan taco, meat rolled out of my taco on top of some sweet potato. It was very evident that the meat was mixed in and cooked with the sweet potato.
The kitchen needs to reevaluate their cross contamination practices to avoiding serving their vegan customers meat.
