The whole point of the Ikea restaurant is that they are show casing a lot of their own products in there: the cutlery, plates, tables, glasses, chairs, tables, etc. are all stuff that they sell in the store as well. I think they have some variations between countries in what they offer exactly in terms of food. So, greasy/bland diner style food is what you get in the US mainly because that is what people would expect to get in a place like that in the US. Likewise, the German Ikea has some German things (I've been there). I do wonder what they would do in a place like Italy. They tend to be super picky there. Serving mac and cheese there would probably get the chef lynched.
