We know of no Las Vegas buffet that kicks out patrons between meals. Most Las Vegas buffets, however, close the cashier stations around a half-hour before the start of the new meal; as soon as the cash registers close, the kitchen staff starts breaking down the previous meal and setting up the new one. This discourages people from taking too much advantage of the changeover.
Still, if you can get in under the breakfast or lunch wires and don’t mind waiting around 20-30 minutes for lunch or dinner, it can be done. And a handful of buffets don’t close between meals. For a full survey of current buffet closing policies, click here.
