My love for tamales started when I was 19 or 20. I happened to visit my friend, and his mom had just finished making her famous tamales and I got to try one. I had never seen or heard of tamales before being from Japan. I just remember it being AMAZING with a mouth full of flavors.
I think Teotihuacan is a must visit place if anyone comes to Mexico City! It's about an hour by car from the city. But, it is worth the experience to take it all in and walk the entire park if you can.
