You're so cool."all that time spent" happened to be as long as 44 years ago, child. I lived in El Salvador in the mid 1970s for a while. Have not been back to Mexico working since about 1990.
When I stop in and Pepe says "I got something you need to try", I try it. I have not had to pay for a meal there in years. ;-)
Is what you try fancy, or typical tex-mex?
