I went to IKEA to pick up a few things and was pleasantly surprised to find their menu items clearly marked for wheat, egg and dairy. The Swedish meatballs without sauce a free from all three as is a salsa chicken plate with beans and rice. It would be worth a bit more research if you need 100% gluten free, but I was impressed with the clear allergen labels and a decent range of options
