It is a bit difficult to be objective about Zacatecas, as I have such an appreciation for their history. My family and I first ate at their original location many years ago and will always have a fondness for Olga and Luz. It has been many years, though, since we have been back, and although the food was still very good and the service even better, somehow the food for me was not as good as I remember it. For starters, the chile Colorado, which is served initally with chips, is a mere shadow of the original. I am sure the changes were economically motivated, but the quality has diminished. The original Chile Colorado was rich with bits of pork, and always immediately made the visit quite worthwhile. Worse than blandness and a watered down quality of the present version, it seems perhaps some sort of filler, such as corn starch has been added. I also found my mole just OK, as it seemed more commercial than homemade. On the other hand, my husband loved his enormous burrito with red and green sauce and I enjoyed sampling it, as well. We both loved being there, but were saddened by not only the passing of the parents/original owners, some history, and that fabulous chile Colorado.
