I too had a horrible dining experience at El Puerto. I love Mexican food (Mama's Mexican Kitchen is a favorite) and this place is close to where I live. I ordered a shredded beef burrito and for the first time I literally could not eat a Mexican meal. It was revolting. My husband said his fajitas were edible but he would not eat there again. The service was very hurried and the waiter did not bother to find out why I had barely touched my meal and did not want a doggie bag.
Pros: location
Cons: food, service
