We just got back last week. One day at MK we ate at Pecos Bills, another day we ate at CHH. I'd take PB's any day, although CHH had more room and slightly more comfortable seating. The food was just so-so -- standard fried chicken strips & fish fillet, an okay tuna sandwich. Slow service even though we were there at an un-busy time (though to be fair, this was something we noticed at all the CS places throughout our trip; odd).
I'd give CHH a "C". Next time we will go back to PB's.
