The Teppanyaki at Japan is not a quick place for lunch. It is a sitdown restaurant and will take at least an hour. Depending on the number in your party, you may be seated with another party. You and they all have to order from the waitress. Again, it's a regular sitdown restaurant and accordingly takes time. There is the Tempura Kiku in Japan where you can get tempura or sushi. You sit at a counter and do have a waitress, but it is substantially quicker - but not nearly as quick as the basically takeout places that ring World Showcase Lagoon, including one in Japan. Any of them will suffice. The Tangerine Cafe at Morocco is relatively new and has wonderful seating with good views if it's a nice day.
