Came here based on the stellar reviews. Food was good, but I don't know if it warrants all the spectacular praise. To each his own, I guess. We ordered chicken and steak tacos, a bean and cheese burrito, and a quesadilla - everything was good and the guy behind the counter was friendly.
Two really good things about Tacos Atoyac is the cheap prices and the no-frills atmosphere. We ordered all the food listed above plus two drinks and the total price was around $15 or so. For that price you definitely get a good quality meal. You also get to enjoy your food in a place that isn't swarming with tourists. Tacos Atoyac is as local as local gets. The inside reminds me of a cafeteria you might find in a juvenile detention facility. Pretty bland, white walls, metal, a small kitchen right behind the cashier, and a few tables. Not dirty at all...just old, no frills. Perfect and really enjoyable.
