Permissibility of entering a place in which alcohol is served
It is permissible to enter a place in which alcohol served, as the following hadith in Kitab Dursat ibn Abi Mansur (one of the surviving 400 usool) - as recorded in Mustadrak al-Wasa’il by al-Muhadith al-Nuri.
A modern context would for example be entering a restaurant which serves other tables alcohol - as long as your table does not serve alcohol.
(Mustadrak al-Wasa’il, volume 17, page 74)
“Kitab Dursat ibn Abi Mansur: narrated from Abi al-Mughara, from al-Hasan al-Nayli, from Abi Abdilah [al-Sadiq]:
I asked him [i.e, the Imam] about people of African origin.
I said: ‘We enter upon them while they are in their tables drinking alcohol’.
He [the Imam] said: ‘There is no harm for you in entering upon them’
