(Reuters) - A U.S. wine merchant went beyond just cursing Gordon Ramsay on Monday and filed a lawsuit against the television celebrity chef who is known as much for his command of swear words as he is for his sauces. The merchant, Wineberry America LLC accused Ramsay, his private equity backers the Blackstone Group, The Righa Royal New York hotel, now called The London NYC, and others of not paying for $40,900 of wine that was ordered and delivered, according to the lawsuit filed in New York.
