I always get a bit of credibility when visiting a Mexican restaurant when I order that. Believe it or not, the Czechs make a tripe soup that is lovely as well. Nice and spicy.
When I grew up in NC, we never appreciated any Hispanic culture at all, other than eating at generic Mexican restaurants. Even though my grandmother was obviously from Mexico, she told everyone she was from Spain! However, when I left home and started living in California and Arizona, I really loved all the new Hispanic culture. That's why it all has a soft spot in my heart, because it reminds me of those good times.
