U2 singer Bono made a surprise appearance at chocolate mecca Max Brenner in Tel Aviv. Spies told us the rocker arrived with a party of 12 on Sunday. “Bono kept his sunglasses on at all times,” said a spy, adding he was “extremely kind to the waiters and guests.” He walked away with some chocolate goodies as gifts from the staff. Bono’s been spotted lately in Israel, where U2 hasn’t played since 1997, and there’s been local speculation that he’s there for either a business or charitable trip.
