Ivana Trump is planning a worldwide restaurant empire after successfully unveiling her first eaterie on the French Riviera. The former wife of tycoon Donald Trump went into business with Iranian heiress LISA TCHENGUIZ after they bemoaned the lack of good places to eat in the resort of St Tropez. It proved a hit and now they want to take on the restaurant world. Trump, 57, says, "Lisa and I were saying, 'There is no good Italian restaurant in St Tropez, let's open one.' "We are going to open another one in New York. A restaurant empire - it would be nice."
