We were there for a concert during the Flower and Garden festival and DD snacked away without a problem. In fact, the snacks were how I bribed her to listen to an "oldies" band with me.
That being said, I don't actually know what the official policy is, and if it changes depending on the crowd. It was a light crowd evening when we were there.
yes, its an open air theatre, we ate our raviolis and drank our slushies while being entertained by Sugar Ray, he put on a good concert, got really involved withi his own stories from home, ect..Mark Mcgrath is a really down home person!!He totally rocked the show!!:O)
