Rich hosts would display their wealth by having expensive meals. Some dining rooms had mosaics showing scraps of food. Sometimes the host would present entertainment. They would have musicians, acrobats, dancers, jugglers, conjurers, and poets for entertainment. For dessert, Romans ate stuffed dates. Dinner had three courses. Slaves would wipe the guests' hands between courses.
Poor Romans didn't even have a kitchen because they lived in the top floors of apartments. They can't have a woodburning stove because the apartment is also made out of wood. They would visit a tavern like you would a restaurant!
