Been meaning to write a review for years . . . we eat here at least 3-4 times/month. The BEST tacos. Ever. And, yes, my wife is from D.F. and we travel EXTENSIVELY throughout Mexico (on the economy, not the tourist spots) and after the first two attempts we NEVER ate tacos anywhere in Mexico again because they are NOT AS GOOD AS LOS FAVS. That's the bottom line. Every time we return from Mexico we immediately drive directly from the airport to Los Favs for tacos.
As to the other reviews: what is a "raw taco?" Are you saying they didn't cook the meat they put inside it? Sorry, but that is not to be believed . . . dipstick. If the food was cold you should have asked them to put it in the microwave for 30 seconds.
Salsa is "not good?" Why? Because it's fresh and has no preservatives? Their salsa is equivalent to/better than some of the best we've found all over Mexico . . . dipstick.
"Rolled tacos" are actually "flautas." So not sure where the nomenclature came from, but I have had them here and they are pretty damn good. Better than many I've had in el D.F., Michoacan, and Chiapas.
Can't comment about the other menu items because we haven't partaken. But they appear to be packed to the gills at all hours with people ordering burritos (which, by the way, are NOT Mexican food) so they must be doing something right on that end.
If you want the best tacos in the Valley (better than those we've found in Mexico and in all the other United States of America) go to Los Favs in Tempe!
