Actually, I judge Mexican restaurants by their huevos rancheros and chile rellenos. If I go to a place that serves chile rellenos, I ask them how they serve it. If they want to know whether I want beef or any other meat in it, I order something else because at that point I know I’m not in a Mexican restaurant. I’m at Chi-Chi’s or Jalepenos or Chipotles or Taco Bell or Azteca. Then, I might as well get a burrito or taco or peanut butter sandwich.
It’s like a Rueben sandwich in a deli. If they ask you if you want pastrami or corned beef with it, order something else. They don’t serve Ruebens there.
