The Plaza Pavilion Restaurant, located about half way between Westernland and Tokyo Disneyland's central hub, serves buffeteria style food with indoor and outdoor seating. Menu items include spaghetti (with a variety of sauces to choose from), grilled chicken, smoked salmon, fried prawns, and other mainstream food items.
Although the Plaza Pavilion is not the most exciting place to eat at Tokyo Disneyland, it is adjacent to the Plaza Bandstand Stage. If you can manage to get an outdoor seat before a show, you may get to enjoy some live entertainment with your meal (the show times posted at the front of the stage).
