I actually really like their meatballs meals. And they serve them with either fries or boiled potatoes, your choice. (I prefer the fries, sorry).
Living in the DC area, we have family visit from all over the country and IKEA (and its cafeteria) has become a "tourist" destination for our family members. In fact, I'm taking my Aunt there this evening, and yes, we will be eating dinner there. I think it's just part of the experience!
