We ate here 3 times during our stay in Antigua, which included walking back here during our shuttle layover on the way back to Guatemala City from Lake Atitlan. Super cheap and yummy tacos. We ordered res and al pastor supreme each time. The place is simple and charming with bright yellow walls and avocado-shaped napkin holders. It's a few blocks from the main square but don't miss it.
