There was one in Austin (on Lamar and 43rd) next to Chili's that I used to hit up back in the day (01-02) before I moved to H-town. It wasnt PF Changs, but still good food in a CLEAN environment with generous porportions. And the prices were good at the time too. I believe 7 bucks for a meal and a drink - not bad.
That Panda Express is still there. It's the most (and best) Americanized Chinese food on the planet. It was also the cleanest fast food joint I've ever been to. That place was spotless.
I just stopped by the one at hwy 6 near 59. It filled me up...that was about it. Nothing special, but the drive thru option is great.
