Is the invitation of a non-Muslim in a restaurant that has intoxicants accepted?

Question:
Young people are invited by adherents of other religions to restaurants where intoxicants are sold. Should they respond to these invitations despite their repetition, or should they decline them?

Answer:
If they drink intoxicants in the place where they eat, and if drinking intoxicants has a separate place, and those who invite them are in other rooms, there is no harm; because people may need restaurants. If the restaurants have sections where one can be secluded with his food from women and from intoxicants, there is no harm.
