First I want to say that the food and service that my kids and I received was very good. This was not the first time that we had been here either and food and service has been very good each time we visited. I was not planning on eating out, but I looked on their website (not someone else's or another coupon site) and saw that they had a coupon for 2 adult buffet $4.00 with purchase of 2 adult drinks. I showed the coupon to the waitress that sat us down and she nodded and smiled. After we finished eating a different waiter brought our bill with no coupon used. I showed him the coupon and he explained that it was a mistake and it should have said $4.00 off. I explained with no avail that I had shown the coupon before getting any food and that if I had known that it was only $4.00 off I would not have chosen to eat there. He was nice as he could be, but it doesn't change the fact that I thought I was going to spend $20.00 I ended up spending closer to $40.00.
