I work evenings at an office building next door to this restaurant.
For me it is a convenient, consistent, and economical option for take out.
I usually order the Carne Asada Fries or the Carne Asada Burrito; it's always good, and exactly what I expect from a Filberto's.
The hostesses are always friendly and the wait time is generally very reasonable.
I expect I will continue to be a regular patron whenever I'm in the mood for some Sonoran street food for supper.
