It's still very Mexican
(Syracuse, NY, USA)
I've been to SMA a number of times and, although its gringo population is growing (or so it seems), it still retains a very Mexican feel, and for good reason: the Mexicans still vastly outnumber the gringos!
This is as it should be. I see no sense in going to the expense and trouble of going to another country just to see a bunch of people that I could see back home, or to eat food that I can get back home. I go to Mexico because of Mexico and all things Mexican.
San Miguel offers this in abundance.
