It cost a little under $20 for two adults! The food was excellent.
Only down side to buffet is it is obviously a big hit (1/2 off Tue & Thu) because we had to wait about 15 minutes to be seated. It only took a few minutes to sign up and off we went. Turns out on Tuesday and Thursday the buffet is half off with the senior loyalty card (over 50). The same employee came back to us and told us the buffet didn't actually open for dinner for another 30 minutes but if we wanted to go sign up for their loyalty card we could get $10 in slot machine money and half off the buffet. She pointed us in the right direction and we headed off. When we entered the Casio we asked an employee where the buffet was located. We were headed north and decided to stop at the Rolling Hills Casino for fuel, food, and maybe a few coins in the slots.
