Good suggestions above! What sort of activities are you into? There’s lots to do outdoors around the area, if you’re visiting in the good season
The new Starbucks flagship store is worth the visit, if not just for the clover There’s also a pizza joint (by Tom Douglas, I think?) in there. But since you’ll be on Capitol Hill, there’s plenty of other good eats. Mamnoon and Trove are two that are less than a block away. For burgers, try lil’ woodies.
I would spend some time to check out a few of the museums. For “DONT MISS” I’d sugggest Seattle Art Museum, and possibly the Frye. Then there’s the Asian Art Museum in Volunteer park (next to a really neat glasshouse, if you’re into plants) with a ton of inspiring works from a huge range of time. Don’t miss their collection of snuff vessels, if you do go. The carving is amazing. For architecture, the Central Library by Koolhaus mentioned above is amazing. GO INSIDE! I learn something new about the space every time I visit. Also on the list of places I’d force friends to see is the Bullet Center, really neat if you’re into green buildings. It’s LEED platinum and also one of the first “Living Building” participants.
Lots of great beer in the area. That could be a whole other post, but if I had to stay in Seattle / Ballard, I would suggest staying away from Downtown. If you’re into cocktails, I’d say make reservations a coupe days in advance for needle and thread. You won’t be disappointed. If you’re up for trying lots of different beers in one place, check out Chucks Hop Shop. Or go up to Ballard to explore Fremont Brewery, Urban Family, or Peddlers. I’d join gladly join in a for a drink! It’s rare to meet ID folks. I mostly run into UI/UX and software development types.
Speaking of which, there are a few firms that seem pretty friendly. I’d say scour your LinkedIn for any way to visit Carbon (and ask for a demo of the new Occulus Rift) or General Assembly.
For nature, I’d recommend making use of some of the great parks in the area. Seward park is one of my favorites, it’s a peninsula on Lake Washington that contains the largest strand of old-growth forest left in the city. Discovery park is huge and has lots of different topography to explore. Golden Gardens is pretty accessible as well. If you want to get a little farther out, get a ride to North Bend and check out Mt Si for a nice day hike.
I find myself hosting friends pretty often, and I can’t say I’ve ever had a dull or boring day. I love Seattle, and I hope you enjoy your visit!
And seriously, lets grab a drink.
