Saw an interview with the soon to be CEO of In nOut, pretty neat story. Still in same family, new CEO is a 30 something granddaughter of the founder.100% company owned stores, no franchises. Will use no frozen products, so will only open stores near a distribution center, which they opened one in Texas a few years back. Link to interview.

BTW, great chicken place in DC that i think will soon be national is Nando's Peri Peri. South African rotisserie chicken, awesome stuff, huge overseas, just in DC now. Some awesome stuff if you like a bit of spice.
