Hands down, the best burrito in the bay area.
I've been a loyal customer ever since I was turned onto to this place. It is in a shady part of town, and it 's not the cleanest place ever (not filthy either though), but the food is amazing. Very soft tortillas, flavorful meat (I always get either Pastor or carne asada) and great accompaniments. I take people here every chance I get and they always like it.
