Is it permissible to enter restaurants that serve alcohol and eat there, knowing that one does not see the alcohol or those who drink it, and that the majority of restaurants in Bethlehem belong to Christians and are open on holidays, unlike Muslim restaurants?

It is preferable to call the disbelievers who deified Christ "Nasara" (Christians) as Allah named them in the Quran, not "Masihis" (Messianics). It is impermissible to enter restaurants that serve pork or alcohol for several reasons, including: the presence of manifest evil, the obligation to denounce evil even in one's heart and to avoid its location, the possibility of consuming non-halal (definition) food or using unclean utensils, the act of endorsing these restaurants and encouraging Muslims to frequent them, and the mixing with disbelievers and increasing their numbers. Such restaurants are not necessary, and one can substitute them with halal food from other places.
