Buffet, Smorgasbord, Viking
noun, する verb
バイキング comes from the English word Viking, but in Japanese, it often refers to a buffet. バイキング came to mean "buffet" thanks to Japan’s first all-you-can-eat restaurant, "Viking", which was named after a feast scene from a movie called (you guessed it) "Viking".
