IMHO, CFA has much much better service than any other fast chain operation I've ever tried.  We sit eating there and I look around and marvel at it and wonder why others can't emulate it.  My guess is they pay well, but I don't know that, and their managers are well vetted.
It's a pleasure to watch, for me.  
We have one 3 blocks away from us, but we prefer dining at local places over chains.
