Torchy's Tacos - this place easily gets my vote for best tacos in Austin. The last 3 people who have visited me have asked to stop there a 2nd time before they left, when they were only here for a weekend. It's that good. Get the queso (also the best in town in my opinion), the Democrat and the Green Chile Pork. For breakfast (or anytime) - the migas taco is also one of my personal favorites.
