Coming together to eat is indicative of happiness, according to the situation at the time of the dream. One of the dream interpreters said that whoever dreams that he was inviting people to a meal is getting involved in a matter that will make him tired.
If he dreams that he invites people to an unknown meal in which there is a lot of fruit or drinks, he will call people to jihad, based on The verse in which Allah says:
“Therein they will call for fruits in abundance and drinks.
