If you're near by Portland, Oregon, this meetup / lecture might be of interest to you:
"Is the brain chemistry behind our love for chocolate equivalent to that which drives infatuation with a new lover, the love of a particular song, or addiction? How does the brain sort out pleasure and discomfort? What drives our decisions to stay with one person for life or go from one lover to another, never settling down? This pre-Valentine's Day Science Pub will focus on these and other questions that reveal much about how neurochemical changes can have major effects on our behaviors — how we love, what we love, and who we love."
The Bagdad is a nice place - vintage theater, 21 and over, with food and drink.
Parking is on the neighborhood streets, so it might be a bit of a walk (a few blocks) to the theater, and this is the rainy season There's a suggested $5 cover charge.
