If you like dumplings hit up Din Tai Fung in Lincoln Square in DT Bellevue - place is always packed and often has 1+ hour waits but the food is pretty damn good. Can either try to get a space at the bar or if you have to wait an hour for a table you can check out the mall or have a drink at numerous places nearby while you wait. There's a bowling alley on the same level that doubles as a nightclub / bar and a poolhaul / comedy club upstairs. Not much for touristy stuff in Bellevue, but Seattle is only 10-15 minutes away. There's an easy waterfall south and a bit to the East of Bellevue (Snoqualmie Falls), about a 20-30 minute drive away and right off the side of the road.
