Although I'd really hesitate to say he has a point (considering his positions which seem to be opposed to mine in every way I can see) it's a common rebuttal to an argument advanced by people who support immigration: that such people bring their culture with them, or more specifically, places that sell "ethnic food". The truth of the matter is that you don't need such people to cook the food for you, and this isn't even mentioning the (in my opinion) rather twisted logic in which we'd want immigrants just so that they can cook their food for us - perform a little dance and show, and not talk too much.
