Okay, I think I get it. I accidentally equated 4900 kr with $71. The former is the per person ISK price for brunch, while the latter is the total equivalent in USD. I've corrected the entry to show 4900 kr = $35.50. The $71 was the total cost for the both of us. Still not cheap, but we've had more expensive brunches back home, at least pre-pandemic when the Peppermill had a weekend brunch that we frequented.
