I'm looking for "hole in the wall" TexMex places in central Austin that do not "Keep It Weird".
This is just my opinion, but most of the widely-mentioned places in this part of town seem to try to "exotic" or "healthy" up the food to its ultimate detriment.
I'm just looking for the untrendy, uncontrived, good old joints that are more like something you'd find on every block in San Antonio.
The best I've found is Jefe's on (7500-ish) Lamar, which is in a stripcenter with a gas station. Janitzio, just east of Guadalupe on 24th, looks promising as well. Open to any more suggestions -- and bonus points for anything closer to the Hyde Park/North Campus area. Triple bonus points for late-night hours!
