A dinner party is a social gathering at which people eat dinner together, usually in the host’s home. At the most formal dinner parties, the dinner is served on a dining table with place settings. Dinner parties are often preceded by a cocktail hour in a living room or bar, where guests drink cocktails while mingling and conversing.[2] Wine is usually served throughout the meal, often with a different wine accompanying each course.

At less formal dinner parties, a buffet is provided. Guests choose food from the buffet and eat while standing up and conversing. Women guests may wear cocktail dresses; men may wear blazers.

At some informal dinner parties, the host may ask guests to bring food or beverages (a main dish, a side dish, a dessert, or appetizers). A party of this type is called a potluck or potluck dinner. In the United States, potlucks are very often held in churches and community centers.
