Best mariachis: Los Torcazos

Why do people rely on reviews to find a place to eat? Wonder around and find a place you like and go eat. F the reviews.

The reviews are just another tool. However, I do agree with you. My favorite way to find new restaurants is to, as you say, wander around and look for places with many locals. Like reviews, it is not a guarantee, but it is so much fun when you stumble upon a real gem. Plus, an added bonus is sometimes you strike up a conversation or two and get to practice Spanish.
