help with idea for art project?

for my art project, i have to learn how to advertise pizza. we gotta create the box, logo, catch phrase..etc.

so i was thinking of targeting families..like a family oriented restaurant. i need help coming up with a cool logo, what the box looks like, and a good catch phrase..i was thinking about san francisco's pizza or something..but i dont know

something about families being able to create their own pizza.

the box has to be sort of fit for a family- which means taht it has to lure kids in while not making it so kiddy like.
