Which term describes someone fond of feasting, drinking, and good company?

The term "convivial" is used to describe a person who is fond of feasting, drinking, and enjoying good company. It embodies an atmosphere of friendliness and lively social interaction, making it particularly appropriate for someone who enjoys gatherings where food and drink are central to the experience.

In contrast to the other options, "socialite" typically refers to a person who is prominent in fashionable society but doesn’t necessarily imply a specific fondness for feasting and drinking. While "gregarious" describes someone who is sociable and enjoys being with others, it doesn’t focus specifically on the indulgent aspects of social gatherings. "Festive" relates more to a celebratory atmosphere rather than directly to an individual's fondness for feasting and socializing. Thus, "convivial" encapsulates the essence of enjoying conviviality with a focus on the joy of dining and drinking in company.
