This colorful and deservedly popular restaurant, a fixture in Nogales, Mexico, since 1927, moved across the border and now serves delicious Sonoran classics in Tubac village. Try one of the five Chicken moles (a sauce using chocolate as its base), ranging from sweet to nutty to spicy, and you'll know why Chef Ruben has such a devoted following. Chiles rellenos, enchiladas, and heartier steak and fish selections don't disappoint either. Save room for the divine flan dessert, a creamier version of traditional Mexican custard with caramel sauce. Live music on Friday and Saturday nights adds festivity to this gem of an eatery in a quiet little town.
