Is it sufficient for a café to be free of shisha and gambling (cards and dice games) for the project to be considered permissible (halal)?

There are two conditions for a deed to be permissible: that it is lawful in its origin, and that it does not cause harm to people. What the questioner is doing is permissible because he is not selling what Allah has forbidden. He must adhere to the ethics of Islam in selling, such as honesty, not cheating, and not lying. And remember the saying of the Prophet, peace and blessings be upon him: "Indeed, merchants will be resurrected on the Day of Resurrection as wicked, except for those who feared Allah, were righteous, and truthful."
