Occidental Park
This shady, picturesque cobblestone park is the geographical heart of the historic neighborhood—on first Thursdays it's home to a variety of local artisans setting up makeshift booths. Grab a sandwich or pastry at the London Plane and people watch from one of the colorful café tables dotting the tree-lined square. Note that this square is a spot where homeless people congregate; you're likely to encounter more than a few oddballs. The square is best avoided at night.
