Taco Veloz is a Buford Highway classic. It's a tiny little drive-in that's open all sorts of hours. The food is very good and pretty darn cheap.
Here are my tacos, one beef and one pork. I also ordered a cheese quesedilla that didn't make it into the photos. The meat was very flavorful and tender. Each was wrapped in two tortillas that were soft and delicious. The cheese quesedilla just plain oozed with flavor. This food isn't particularly neat to eat, so be prepared. But it's a great spot to grab a bite to eat.
