I ate at the Graden Grill last October. I loved it! We were a group of 5 adults, and the characters were very attentive to us. They all came around at least twice and were very interactive.
I liked the food a lot, too. It was served family stayle, and tasted very fresh. The catfish had a sweeter tasting breading. The menu has changed a bit - I think they now serve pork, but we had turkey at the time we were there. The sides are good too - love the stuffing and sweet potatos!
We were re-hitched at our lunch, so in addition to the regular dessert (which changes often - we had bread pudding), we were served an anniversary cake, too!
