Working in a Restaurant is not ḥarām itself but it is impermissible to sell ḥarām food and drink.
Question: What is the ruling on a Muslim working in a restaurant in which he must serve alcohol to patrons of the restaurant?
Answer: It is not permissible to do anything in connection with alcohol or wine.[1] There is no problem in working in a restaurant in non-Muslim countries. However, it is impermissible to sell ḥarām food and drink, even if the customer does not see problem in consuming them.[2]
