There are hundreds of places to eat in Las Vegas - nearly every hotel offers a great breakfast buffet.  Some of those buffets that stand out are the buffets at Excalibur and Harrah's  Both have a great selection of food, a price that is relatively inexpensive, and the restaurants are clean - always important!

If you're looking for a great place for sit down service, Sherwood Forest at Excalibur offers delicious breakfast choices at terrific prices while America at NY NY offers typical "American" breakfast fare at reasonable prices.  The restaurant boasts a hanging map of the United States that you must see to appreciate.
