Try any other location - skip the Summit!!.
We were thoroughly disgusted by our experience at Qdoba in the Summit. After eating there today for a quick lunch, we noticed several major health violations. A worker touched a trash bin and then handled soft tortillas on a food prep station with her bare hands. A manager dropped chips onto the visibly dirty cash register station, picked them up, and placed them back into our chip basket, all with her bare hands, with which she had been handling the cash register and other items around the kitchen. When asked for new chips, the manager said "REALLY?!" in an incredibly disrespectful manner. In fact, we were treated as rudely as if the manager did not understand why this was a clear health violation, which is very troublesome in itself!
We have seen several other instances like this. This is a popular restaurant, and if that is how they handle food under the watchful eye of customers, how are they handling food in the back of the restaurant? This has disgusted us enough that we worry about the overall health standards and want to warn people to avoid due to these major health issues and this particular Qdoba's obvious disregard for sanitation.
It's a shame because the food can be quite good, but nothing is worth the chance of becoming ill due to unsanitary food prep conditions. I have already contacted the health department and hope this problem can be fixed in a timely manner, but we will still never go back.
