Well, maybe my Google is better than yours :p
Seems to be every food place calling itself El Charritos serves mexican food, have also read that Charro (Charrito is just the diminuitive of Charro) style cooking was originally food charred over a grill...
El Charro's are the Mariachi type of cowboy - according to most info out there. The link is probably their method of cooking while out looking after the herds I'm guessing. Just a thought
Here's a piccy of an El Charrito :)http://th09.deviantart.net/fs11/300W..._by_TOTOPO.jpg
