One of the must-do-thing when going to Ikea is to have lunch there. It serves very common Northern European dishes: potato with meatballs or salmon. The annual sales from its restaurants contribute to about 5% of its revenue. I particularly like its Swedish meatballs which are smaller than Norwegian ones, reminding me of the Chinese dim-sum: beefball. With the traditional Lingonberry Jam, Lingonberry Jam，I can eat 16 pieces each time. If not enough, we would buy a bag home.
