Ditto on liking the meatballs. I haven't had "real" Swedish meatballs, so I have nothing to compare them to. But for the price, they are tasty. I've even bought some to make at home.
As for the other dishes, they are so-so. The chocolate torte cake wasn't chocolately at all. The chicken is decent. I don't normally go to IKEA just for the food (it's a bit of a drive for me), but if I'm going there anyway to get something, then I'll enjoy a meal there.
I'm referring to the Orlando location, btw.
