Seattle Sea-Tac Airport:

There’s good coffee galore in the Seattle airport, but also a few surprising shopping gems.

Butter London Nail Salon: Most random–yet awesome–airport shop ever? Get a mani or pedi ($20-$25) with some of Butter’s signature sparkly colors while you’re waiting, and pick up some polish while you’re there–the brand is hard to find anywhere except online here in the US. They even do eyebrow waxing.

Fireworks: An award-winning and quirky artsy/craftsy Seattle shop (there are 6 locations in the area). You can grab a gift for anyone here, from your little niece to your grandpa. They even have a whole section of custom-made flasks. (A necessity for any airport experience these days.)
