The Gospels mention Jesus dining with tax collectors ("publicans") and sinners in a few different locations, usually in the context of someone's house. Here are some key examples:
* Matthew's House: The most explicit example is in Matthew 9:10-13, Mark 2:15-17 and Luke 5:29-32. After calling Matthew (Levi) to be a disciple, Jesus dined at Matthew's house, with many tax collectors and other "sinners" present.
* Zacchaeus' House: In Luke 19:1-10, Jesus invites himself to the house of Zacchaeus, a chief tax collector in Jericho.
The Gospels don't always specify the *exact* house or location when Jesus dined with these groups. The *point* of these stories is more about who he was dining *with* (and the criticism he received for it) than the specific address.
