A buffet begins with somewhere to put the plate

A buffet is a sequence of small hand movements. Someone picks up a plate, chooses food, finds utensils and looks for a place to sit. Arrange those movements well and an informal meal feels easy before anyone notices the styling.
Put a stack of suitable plates near the beginning of the route. Leave generous space for the actual dishes, then gather napkins and cutlery near the far end so people do not need to juggle them while serving. Check the route with a plate in your hand, including the point where two people might meet.
Use serving utensils that suit each dish, and make ingredients and allergens clear to guests. Follow appropriate food-safety guidance for hot or chilled dishes; a beautiful sideboard does not provide temperature control. Set out smaller portions and replenish appropriately rather than assuming everything can remain there for the whole evening.
The dining table can stay simple: glasses, comfortable places to sit and perhaps one low vase. Keep drinks away from the busiest serving point if the room allows. Good hosting is often a matter of removing one awkward movement, then giving the food and conversation room to happen.
