Bay seniors who appreciate the benign neglect that allowed downtown Oakland to avoid the architectural disasters of the mid 20th century, will want to sign up for a tour of the gorgeous Howden Tile Building. Built in 1925 it’s an art deco gem now housing the Spice Monkey Restaurant. Sponsored by the estimable Oakland Heritage Alliance, the tour/talk is January 12 from 10 to noon. $35 including lunch. Limited to 40 so don’t procrastinate.
