I actually quite like the breakfast buffets, offered by 5-star/resort hotels.
I once stayed at the Rasa Sayang hotel in Penang, where they served a mouth-watering array of breakfast meats, eggs, pancakes, breads/crossiants, cereals and fruits in an open-air dining area in the gardens, near the pool.
It opened around 6:30am and carried through right until lunch. It seemed like a waste to me, actually. They had mountains of food leftover, which probably got thrown out or served up again the next day!
I might have to change my vacation plans and come to Vegas, to sample the decadent "buffet" lifestyle.
