Don't know about the others, but Cracker Barrel closed about 2pm 

Well we didn't know reservations were needed! That's a first for us at any restaurant in KW. Plus the first timee we ate out on Xmas Eve. DH called for closing hours at Mencius. They said 9:30 but made no mention about needing Reservation. So, when we showed up, we got turned away. DD called across the street to Oriental Gardens. It was open and they said we didn't need reservations. Sweet! We drive across the street and we were told we needed reservations so out we went along with another couple who didn't know either! We made it to Hins cuz andrew told us to. He was right! It was open. And dinner was fun and the company even better. Now, fat and happy, we're waiting for Santa.
