What is a good theme for a seven course meal?

You could take your diners on a culinary world tour with a dish inspired by each of the seven continents of the planet, or stick to the cuisine of one area or region. You could choose a movie theme. Serve dishes from one time period, the 80s, the 40s - whatever, or, journey through time as your meal progresses. You can have a silly, tacky theme, or be classy and sophisticated. Ensure your theme can provide a good main course and work the rest of the courses and other theme elements around that; apples could be a good theme, pork with apple sauce could be your main dish, but chocolate, while a great theme, is harder in a main course. Remember to consider your guests' dietary requirements.
