An insider tells the Daily Star (we know, taking a big grain of salt here): "Alongside the normal menus, Harry has put in his own special request of one sushi meal and five cups of green tea a day. His pal Nick Grimshaw initially got him into it, but the other boys are now betting money on when he'll crack."
The source added, "They want none of the sushi and green tea, and find it funny he's asking their chefs to prepare what they consider girlie food." Sarah Nicholas, who cooks for the band on tour, added, "Harry is the most adventurous eater. He likes his Asian food and fish."
