For their weekend edition, which comes out today, Daily Candy blurbed the house tour, and when Daily Candy blurbs something, things sell out lightening quick. I would pick up tickets soon if you don't have them: Clinton Hill House Tour What: Ogle twelve rarely (or never) seen, beautifully restored mansions and apartments from 19th-century millionaires like the Pratts, Singers, and Pfizers. Why: To the right, a room designed by Tiffany & Co. To the left, your broke ass. When: Sun., noon-5 p.m. Where: Tour starts at St. Luke’s Church, 259 Washington Ave., b/t DeKalb & Willoughby Aves.
