Just had lunch at Casa Garcia's on Wm. Cannon. I've driven right past it dozens of times (usually on my way to Hao-Hao).
Today on a whim I pulled in for lunch. I had the pork in red chili sauce plate. with both corn and flour home made tortillas.
It was seriously delicious. I've been in south Austin for almost 10 years and I can't believe I haven't heard people ranting about this place.
