The Japanese have a knack for taking something, be it coffee or denim, and mastering the art to perfection. A great example of this is yakiniku, or "grilled meat". Few places do yakiniku better than よろにく ("Yoroniku") in Tokyo. Each slice of beef is perfectly prepared and grilled right in front of you. Just make sure to try and save room for dessert. LINK.
