This group of tourists is on the Underground Tour which takes place in Pioneer Square. This tour is quite fun and I recommend it when you visit Seattle. Also, if you want to spice it up a bit, try the Underworld Tour. When you are a local, however, it can be a challenge maneuvering around the crowds!
Imagine my surprise to see this under the counter at Cafe Paloma! See the strip of film for size reference.
