This is OK. Not more, not less, just OK. It's a total rip off from IKEA. The same food, the same…read morelayout, and almost the same furniture as well.
Not very pricey, but not the best food in the world either. Acceptable if you're at Gekås (or Ullared), but if you're not inside yet by lunch, try some of the other spots outside of the huge store instead. I'm an almost native, so I know what I'm talking about having been to Gekås at least 4-5 times a year since I was a kid.
Eat here if you're not done in Gekås by lunch, don't eat here if you want great food with lots of taste, since it's only really the same as at any IKEA.
