Sweet 16 party game ideas?

Okay, so my sweet 16 party is coming up and I'm having it indoors in my huge church. So we are going to have music and food.. but that's all I've got so far. We are also going to play manhunt when the sun starts going down. SO, I was wondering if you guys had any simple, UN AWKWARD, non childish games I could play at my party. There's going to be plenty of people and some adults there. I want something super fun and unique bursts of fun hehe. THANKS.
