We stayed at the Golden Nugget for three days and had a chance to enjoy the buffet twice; both times for breakfast.
The service was exceptional but you can't really screw up serving coffee or juice (well, maybe you can, but this was definitely not the case here during our visit). We found all of the breakfast items, as well as all of the items on the buffet, to be very high quality. Hot foods were hot and cold foods were cold. The freshly made to order omelettes were very good; the ingredients very fresh.
This made us very happy. We would definitely go back.
