It might be worth it for some of those meat balls at lunch. Horse meat or whatever, those things are good.
I can confirm their veggie balls are delicious, too. And free of horse meat.
It's not on the menu, but you can get the mash, sauce and lingonberry jam with the veggie balls. So yummy! The on-the-menu veggie option is the veg balls with pilaf. It's OK, but I prefer mash!
If you get there early enough, you can get breakfast. Basically a full English for £1.50 (£2.25 if you go large) for Ikea Family card holders. Plus, free tea!
