We did Hungry Bear in May over Memorial Day weekend (Sunday night). My daughter and I are also gluten free due to celiac. As far as I know, all of the adult entrees for the F! package are gluten free. I had heard some negative things here about the food, but ours was great. Maybe because our pickup time was the earliest available, 3 p.m., our food was very fresh, hot and delicious. I had the salmon; she had the pork riblets and her friend had the chicken. You can also order off the regular menu, and they have a gluten-free friendly hamburger bun. Adults cost is $30, kids is $20, and that includes a drink. We liked the HB seating area, and it was surprisingly empty-- the BB area next to us was packed like sardines, but there were only two rows in our section, and we were encouraged to sit down. We sat on our sweatshirts to soften the cobbles.
It was a great view and we voted it to be a great deal!
Here's a link to somebody's blog talking about their experience at HB, with pictures:
