I was here recently, for lunch, with my wife and son. We each got a burrito. My wife had a chile relleno burrito and my son and I both got zacatecas burritos. The zacatecas burritos were very flavorful, with lots of perfectly cooked grilled onions and tender generous portions of succulent carne asada. No hard bits or gristle to be found. My wife enjoyed her chile relleno burrito as well. The burritos were standard Tucson size (massive) and the price point was reasonable.
The lady taking the order was very pleasant and efficient which makes for a plesant start to the meal. We took our food to go and will be back to sample more of their tasty menu.
This restaurant, Taqueria El Pueblito is actually on the corner of Fort Lowell and Campbell streets located in a shopping plaza.
