There's a good food truck on Glenstone/Bennet, i think it's called El Ranchito Mío or something like that? Maybe just El Ranchito. I have gotten tacos de carnitas and tacos al pastor. A lot of the time i order just three tacos and they give me four. They have other stuff besides tacos too. I would say the place is definitely authentic, i sent pics to my Mexican Spanish tutor and she agreed que sí es auténtico.
