Tips from locals
Cute used bookstore, located close to restaurants in the area. Great place to hang out while they're preparing a table for you at Toulouse Petit!
Hit the $0.50 rack - I've found some winners there. A great place to duck out of the rain (this is Seattle, after all) and peruse the selection.
