I agree with Jiri on the Pop museum, especially if you're a Nirvana fan, but even if you're not it's worth checking out.

Archie McPhee is probably the weirdest store I've ever been to. It's kind of like one of those old San Francisco stores we used to have in malls here, but turned up to 11. It's a good place to get cheap Seattle novelties to bring back as gifts. Who can't use a devil ducky or two?

If you like MEC, REI is the US version and it was founded in Seattle. Their main store in Seattle is huge and really great. Kind of just a bigger MEC, with more brands, but even with the crappy Canadian dollar there are some good deals on high quality outdoor clothes and gear.

And I highly recommend the Underground Tour. It's a little cheesy... but still completely fascinating and gives a great overview of the early days of Seattle and why people from Seattle hate people from Tacoma.

Seattle really is a great city. One caveat, the traffic is terrible! It's just insulting to be on the interstate going 10 miles an hour as you pass a speed limit sign that says 70MPH. Plan a lot of extra time to get to your destinations, regardless of whether you're driving yourself or taking transit/cab/uber.

Edit: Just realized you said you're going for a stag. Most of my recommendations were more with a family/couples trip slant. The bit about traffic still applies and you might need REI if you discover you've some how lost all your clothes after a particularly epic night.
