For a foreign keys you have to specify an on_delete attribute, food=models.ForiegnKey(Food,on_delete=models.CASCADE)
If a row in the parent table(food for example) is deleted this will cause the row/s that refers to that particular food item in your Restraunt model be deleted. on_delete can be given other options as SET_NULL,DO_NOTHING. Refer the docs they are extensive on this topic.
