2. The World Showcase is Where All the Best Dining and Entertainment Is
While Future World is certainly filled with exciting rides and perfectly fine dining options—not to mention all that free soda you can drink at Club Cool!—the World Showcase is where you'll want to go for the greatest selection of cuisine and entertainment.
Every country has its own set of restaurants (both counter-service and table-service) that all smell so good as you walk by that you'll be tempted to try them all. As you make your way around the lagoon, you may even be surprised with street performances in certain countries, such as an Jeweled Dragon Acrobats troupe in China, live bands playing on the Canada and UK stages, a mariachi band in Mexico, or the "Serveur Amusant" comedy/acrobat show in France.
Some places have both excellent food and entertainment, such as Biergarten in Germany, where you can feast on a buffet of German food at communal tables while a lively band plays Oktoberfest-style folk music.
