I visited this place with a group. Three buffet style meals were rolled into our stay at Clifty Inn. While there were many things on this buffet, I have to say the dinner dessert buffet and the lunch time meat loaf were the best things they had. Everything else was just meh.
The staff was attentive. The dining room is large. With the large group we had and the amount of employees that were staffed, they could've cleared the table sooner. As people finished up their plates and made a second trip, things started to get crowded! It's my understanding that this restaurant is open to the public as well(not just the Clifty Inn goers). With that, I wouldn't recommend this place at all.
The food isn't necessarily bad. There has to be a better option somewhere close by. They have a salad bar, a meat/fish/pasta variety bar, and the dessert section. If you are coming here on a retreat with a group and want to pay for your meals with your stay... this place takes the hassle out of finding a place to eat every day.
