This is just for the restaurant upstairs, the rest of the store is pretty good.
I've rarely seen places that close half their capacity during mealtime but ikea does it all the time. Three times I've come by to grab a late lunch on a weekend and every time the line has been back to the elevator because only one side is open. At that capacity you're looking at 30 minutes to get through, I like some meatballs and almond cake but not that much.
I used to come and get lunch then walk around to see if there was anything I needed, now that I know I can't do both in a reasonable time I go somewhere else.
