Help me decide what to do for my 14th birthday party?

Ok so I am turning 14 on sunday and its not really a party but yeah :P my parents are taking me shopping, and then i'm thinking movie + dinner at the spaghetti factory with 4 good friends? So yeah should I just stick to the dinner/movie or can you think of something really cool and fun to do???? :DD Nothing too expensive, the cheaper the better xD not cheap quality though.... I want it to be fun........but you know;)
