The short hallway between the "Pool Room" and bar acted as a sort of cosmic, generational media portal Wednesday night at the Four Seasons, where a pair of cocktail parties — one celebrating Larry King's 50 years in broadcasting (a.k.a the "old people room"), the other celebrating the New York Observer's redesigned paper and Web site (a.k.a the "kids room") — were in full, boozy, media-centric swing. Some notable no-shows: Fox News chief Roger Ailes (who had RSVP'd) and King pal Don Imus, NBC's Brian Williams and CNN's Anderson Cooper, Wolf Blitzer, Soledad O'Brien, Miles O'Brien, John Roberts and Paula Zahn, who were in Blacksburg covering the Virginia Tech shooting.
