The Issue

Is it permissible for a Muslim living in a non-Muslim country to eat in a restaurant that serves wines, pork and other forbidden foodstuff?

Ruling

It is not permissible for a Muslim to eat in restaurants that serve forbidden foodstuff such as wines and pork when other restaurants that do not serve these are available. However, if it is not easy for him to eat elsewhere then eating in such restaurants is acceptable, provided that he does not eat or drink anything that is forbidden. This is the view of the Permanent Committee for Research and Fatwa[1]

Evidence

Eating in restaurants that serve such forbidden foodstuff helps their owners in what promotes evil and transgression and God has forbidden such help.

 Permissibility when an alternative is not available is based on necessity.
