PF Changs is going to oversaturate the market like Taco Cabana did and I'm about as impressed with Changs as I was with Cabana.
Wha..... PF Changs has one location in OKC and two Pei Wei locations. Calling the addition of a Norman location is oversaturation is quite a stretch.

And comparing PF Changs to Taco Cabana is like comparing Western Sizzlin' to Saltgrass Steakhouse...... Norman needs a PF Changs or at least a Pei Wei.
