Mark Wahlberg and director Michael Bay kept getting their conversation interrupted by fans over dinner at Sunday restaurant in Chicago last week. Sources tell us patrons in the room “went nuts” upon seeing the pair, who were sitting at a big table with a group. “So many people came up to them that eventually the restaurant had to stop photo requests to give them some peace,” a spy reports. They will be filming the big-budget, explosive-heavy “Transformers” in Chicago until October.
