Date Night Ideas

Thanks to accrued babysitting karma points, I have an upcoming date night opportunity next Saturday 5-10pm. Five hours is a pretty big time slot.

Our first idea was to go to the Seattle Art Museum, but it closes at 5pm. Even the new Seattle Public Library closes at 6pm.
The second idea was to take a cooking class. However, neither NuCulinary, nor Sur la Table nor Whole Foods nor PCC have anything going on that evening.

So, the current working suggestion is a movie, but I think we can do better and am hoping you can help. Do you have any ideas?.
