Illustrative buffet dining scene.
At a Las Vegas buffet, a few dollars per person is a reasonable starting point for attentive plate clearing and drink refills. More is appropriate for especially good service. You don't need to automatically tip the same percentage you would at a full-service restaurant.
Buffet tipping is one of those Vegas questions that sounds simple until the payment screen asks for 20% on a meal you carried to the table yourself. The answer isn't zero by default, and it isn't automatically 20%, either.
What are you tipping for?
Buffet servers may not take your entrée order, but they're often doing plenty while you eat:
- Clearing used plates so you can make another trip.
- Refilling water, soda, coffee or other drinks.
- Bringing requested items and keeping the table organized.
- Helping with questions or special requests.

Buffet service still involves real table work.
How much should you leave?
There isn't one mandatory buffet tip. A practical approach is to consider the size of your party, how long you occupied the table, and how much attention the server provided.
- Basic service: A few dollars per person is a reasonable starting point.
- Attentive service: Consider more when drinks are consistently refilled and plates disappear promptly.
- Extra help: A larger tip makes sense when someone handles special requests or goes out of their way to help.
What about Wynn, Bellagio and Bacchanal?
The same principle applies at upscale Las Vegas buffets: tip for the service you receive, not simply because the buffet itself costs more. An expensive buffet doesn't automatically require a percentage-based restaurant tip when you're collecting your own food.
I particularly recommend the buffet at Wynn. Our experiences with the service there have consistently been excellent, which is one reason we tend to tip toward the higher end of our personal range.
Cash or card?
Either can work. If you're paying before you're seated, leaving cash at the table afterward lets you decide based on the service you actually received. If a tip is already included in your bill, check that before adding another one.

Cash at the table is one straightforward option.
Do you have to tip 18–20%?
No. A percentage prompt on a payment screen is a suggestion, not a universal requirement. A buffet involves a different level of table service than a traditional sit-down meal, so a flat per-person amount is perfectly reasonable.
And if the service is outstanding, there's nothing wrong with tipping more. The point is to make a deliberate choice rather than letting the payment terminal make it for you.
