Wonderland tea party?

I need ideas for my Alice in wonderland tea party. I don't know what to serve to eat. I know my party will be from 4pm to 10 pm in my friends backyard. The beggining will start out as a normal tea party and turn into a rave when it starts getting dark out. I'm making my friends dress up semi formal but it has to be bright and wild colors to stay with the theme. I I also have about 5 friends dressing up as characters from the movies. Any othe ideas for entertainment and food? Any suggestions will help
