Kristen Bell was so taken with the food at organic vegan restaurant Candle 79, she begged staff to open an LA branch. A witness tells us the actress, dining last Thursday with a girlfriend at the Upper East Side eatery, “called the owner over and raved about the food, and suggested that she open an LA version of the restaurant. She offered to be an investor.” Bell, once voted the world’s sexiest vegetarian, was in the city to promote her Showtime series, “House of Lies.”
