TWO YEAR OLD BIRTHDAY PARTY IDEAS...HELP!?

my daughter is turning 2 on oct. 17th and we are having her party in a large banquet room at a local restaurant. we are trying to think of ideas/activities for the children attending. i don't know where to start. i really was thinking about having someone do animal balloons but the only ones around here are clowns but I didn't want a clown. what games or activites do you think would be appropriate for kids ranging from 2-6?
