If you have kids, take them! If you don't, take someone elses! If that fails, do as I did and go and see it as a proud person really too old for a U film! ;D
It is fabulous! One of the best films I've seen in a long time, and one of Disney's best films of recent years. It's about a rat who helps a boy to become a master chef, yes it does sound bizarre, but it is sooo cute and funny and lovely so GO GO GO!
