Before my sister and I went touring through IKEA, we had lunch in their restaurant (I haven't eaten in their restaurant before). It was quite busy.
We both had Swedish meatballs (there were 10 to an order) and mashed potatoes.
Surprisingly it wasn't bad. With a pop (refillable for free), it came to $7.90 (including taxes). I think the red stuff was supposed to be cranberry sauce ... it was more like a sweet jam. The pop was really really warm so needed lots of ice.
I'd eat there again if I was at their store and hungry.
