Casa Oaxaca is a Mexican restaurant in Santa Ana. The other moles at Casa Oaxaca are also must-eats: the spicy coloradito, chocolate-infused negro and estofado, a brownish mole created with almonds that I actually enjoy more than the amarillo. They demand your immediate attention, but Casa Oaxaca is one of the few restaurants where you must work through the entire menu to fully appreciate its greatness, as each entrée reveals a different facet of the best regional cuisine in the Americas. Don't bother looking for burritos here, and don't be surprised when the chile rellenos (bloated with ground chicken) and enchiladas (topped with stringy, slightly sour cheese called quesillo) you order are like nothing you've ever tasted.
