Consumption is a process that differs from person to person and product to product. Consumption action means to end in the basis, and when considered economically it means to end the need. In this regard, especially given the differences in food consumption that have occurred in the past two centuries, determining how food needs are formed and what is affected has an importance for many disciplines, primarily health, economics, marketing, anthropology and tourism. In this context, this study has been aimed at understanding the nature of eating and how food consumption occurs away from home as a modern habit. It has also been determined which “social groups”, specifically considered an important factor in the formation of consumer behavior, have an impact on the choice of food and whether this effect differs between consumer groups. * This study is derived from the master's thesis "The Group Effect on the Preference of Eating in a Restaurant".
