Answer:
(Fatwa: 1258/1258=M/1429)
The products you deal in include, according to you, halal and haram items, then all of your salary shall not be regarded haram. As far as haram products are concerned, you should excuse clearly to the owner of restaurant that you will not prepare the haram items. There is no wrong in preparing the halal items and the salary also shall be halal.
