Iron Man himself, Robert Downey Jr., took time out from promoting “Iron Man 3” for some quality time with his dad Robert Downey Sr. Spies said the actor met his father at Park Avenue Spring on Monday. A witness reports, “The pair, who had security with them, enjoyed a casual lunch of steak and garden salad. They were in good spirits and joking around.” The film, which opens nationwide Friday, grossed nearly $200 million in 42 other countries on its opening weekend. [Review in Pulse: Page 33]
