RE: Breakfast buffet ...
Once. At the Airport Hilton at Rome, Italy. Amazingly diverse ethnic food. In addition to American/British-type stuff (eggs, potatoes, grilled tomatoes, sausages/bacon, there were Asian and Indian foods, plus a variety of cooked vegetable dishes that I couldn't identify. Also, a huge selection of sliced cold cuts that were Italian and German. All kinds of fruits. Pastries were excellent and varied. The best part was that the breakfast was included in the room rate!
