Best view is from Rose and Crown. I believe you can also see part of the show from Tokyo Dining and Les Chefs, but not the whole thing. The new Mexican TS restaurant should also have views when it opens.
International Dinner and IllumiNations Desert Reception:
This event offers international cuisine. Following dinner the children in the audience are invited up onto the stage to hear a classic Disney story by the bookmark storyteller. After the story there is a character meet-and-greet, a dessert reception and VIP viewing of the IllumiNations fireworks. The International Dinner experience is available on selected evenings at Epcot. Adults (10 and older) $59.99, children (ages 3-9) $24.99.
Dessert Reception private events:
You can host one- arranged through Dining and Special Events- for your group. There is a venue fee of about $250 and a per person charge for the type of food you choose- dinner, desserts, etc.
