Disgusting!!! I feel like throwing up. I am NEVER eating at any Roberto's Taco Shop again. My husband ordered me a carne asada nacho about half an hour ago (to-go)....ate it and on the bottom I found a fried "tie knot closure" that belongs on a plastic packing bag. Are you kidding me? I will be contacting the Clark County Health District. How unsanitary is that place or their workers? If I could I would leave no stars. It doesn't matter if you're busy and it's chicken taco Wednesday. This should never be in anyone's food. Date: 1/6/2016 @ 9:44 pm.
