The Neptune theater is in the heart of the University District. It hasn't changed in the whole time I've been in Seattle. Many independent films are shown here as part of the Seattle Film Festival. There is a rumor that the place is haunted but I haven't seen anything... yet.
They had 7 days left in their old location when we visited. The exhibition space was small but we sitll managed to spend 1.5 hours there. There is a lot of reading to do. The exhibit that I found most moving was that of Japanese internment camps.
This is a nice activity for the whole family. You will discover lots of things to do. They have many different rooms. You will find something that is your favorite. Everyone (including my 7 year old) enjoyed the trip.
