IKEA is known for being an affordable place to shop, so having that be the answer as an "unaffordable" location is not really fair.

The answer was in the spot where they always put joke answers to the first question, and everyone including the host laughed at it. Combining that with the description of cost being the opposite of what IKEA is known for and markets themselves as, that option is off the table. It would then just come down to which of those 3 cities the guy thought Buzzfeed might have randomly mentioned once as being associated with meatballs.

I think they should let him have another chance on the show.
