Just 708 meals away from their target, the 142-year-old Old Homestead steakhouse will likely see their 10 millionth customer tomorrow, and are planning to celebrate the "Mega-Mignon-Aire Day" with free steak. The lucky carnivore who walks in at just the right moment will receive free dinner and drinks for two, every week, for life (triple bypass coverage not included). Amazingly, reservations are still available for two all day long tomorrow. Owner Greg Sherry told the Post, "We have been waiting since 1868 for this."
