I think I know a bit about Mexican cuisine. Lived in Cuernavaca for nearly a year and helped manage a large Mexican themed flea market with two Mexican restaurants. Since closing it thanks to the Arpayaso I have constantly struggled to find good tacos particularly in central Phoenix. You will not be disappointed, taco chelo is the result of two creative geniuses putting their heads together to create an upscale taco destination. Everything is excellent. You must try it.
