US Open champion Rafael Nadal showed he’s as superstitious as every other tennis player — by eating the same meal at the same restaurant every night before his winning matches.

Sources tell us Nadal dined on Chilean sea bass, fried rice and noodles at Tao in Midtown every evening that he wasn’t playing a night match, including on Sunday, before his finals battle against Novak Djokovic.

After his 2013 US Open win, Nadal and a large group of 20, including his longtime girlfriend Xisca Perello plus family and friends, made their way to Tao to celebrate the victory with a late dinner. The owners kept the kitchen open until 12:30 a.m. to accommodate the champ.
