BEN BRUSEY, author of Pu Pu Hot Pot, likes to eat food at restaurants when he can. He also likes to compete in eating challenges and his record is thirty fish fingers in one sitting (plus mayo, lemon and ketchup). His favorite restaurant in London is the Phât Phúc Noodle Bar, located near South Kensington. "Phât Phúc" translates as "Happy Buddha". Seriously.
