Most people staying in Las Vegas will eat at buffets at some point. Most hotel buffets don’t close down between breakfast and lunch and lunch and dinner; so if you arrive just before the end of one sitting they will switch the food over. As usually breakfast is the cheapest and lunch is next cheapest and dinner is the most expensive you can pay for one and eat food off the next meal. Also by doing this you are eating off peak so the lines are usually smaller. Another tip is to check the free show magazines for buffet coupons, usually the cheaper buffets have coupons for a dollar off per person which can add up for a group. Also when checking in at your hotel ask if they have a fun book which usually will give you discounts of 2 for 1 buffet coupons.
