DS is having his 11th birthday next Sunday at our local Family Fun Center (arcade, minigolf, go karts..) at 1pm. I did put "Luncheon served" on the invitations, because I wanted parents to know that we will be feeding the kids. I always provide food, but I also specifically list it on the invites. Most parties my kids attend are cake/ice cream types with some chips or snacks perhaps. I wouldn't expect food to be served unless it was noted on the invitation.
