We attended the BBQ last summer. Our kids were 2 and 7 at the time. I agree with previous post that the food was average. Nothing special, but not bad either. If it were just my husband and I, I would probably say we wouldn't bother doing it again. Having said that, my kids LOVED it. They had the best time. The characters came out several times and would dance with the kids. Watching my daughter, 2, holding hands with Minnie Mouse while dancing and smiling like crazy made it completely worth it. The character interaction is different than other character meals. The characters dance, take a break and then dance more.
They do play country music which is fine by me. My husband doesn't like country music but didn't care because of the smiles on our kids face. If you go, don't forget your camera.
