Assalamo alaikum Ustadh , is it permissible to take a few extra sachets of ketchup and other condiments back home from the restaurant if we havent used them in our food over there, which were provided to us for the food that we ordered

Ustadh AbdulAziz al-Haqqan

If you mean the sachets that come with the food, this is allowed to take, same as when you order online from them they will give them as well correct? If yes, then it is allowed.
