Officials in a New Hampshire city have approved a restaurant sign that initially was removed over concerns that it sounded like profanity. The name of the Vietnamese restaurant in a public building next to City Hall in Keene is a play on words. It calls itself by the name of a soup, which is spelled P-H-O, but is pronounced “fuh,” followed by the words “Keene Great.” It’s scheduled to open March 1. City Manager Elizabeth Dragon said in an e-mail the sign was approved Friday and is in compliance. She said no one had submitted written permission to put up any sign until Jan. 4.
