Ordering tako or taco (both pronounced similarly) can have very different results depending on where you are. If you're at Taco Bell, you might receive a tasty meal of ground beef, lettuce, tomatoes and cheese in a corn or flour tortilla. On the other hand, the same order in a Japanese cuisine restaurant, will find you enjoying an aquatic animal with several legs. Tako is a Japanese word meaning "Octopus". As Japan is a nation of islands, much of it's cuisine comes from the sea. While enjoying a delicious meal in a Japanese restaurant, part of the fun involves seeing the many items on a colorful and vivid menu and learning their names in Japanese!
