バイキング alone usually means 'Viking' or 'buffet-style meal'; here it is part of the wasei-eigo compound アメニティバイキング, meaning a self-serve amenity station, not a food buffet.
Wasei-eigo (Japanese-made English) from 'amenity' + 'Viking', modeled after the use of 'Viking' for buffet-style service. The exact origin is uncertain, but it likely arose in the hotel industry to describe a self-serve amenity setup.
