The stewards ferrying chilled mugs of beer at Chowpatty's Café Ideal have no clue how and when four pillars stationed on the footpath outside sprouted Warli art characters, and the message, Tribute to our Martyrs of 26/11. A memorial for constable Tukaram Omble, who lost his life in the terror attack, across the road, is fenced by similar pillars, but these stand bare. The cops stationed 24/7 nearby say, "It seems like someone must have come at night and done this."
