Liza enrolled at the École hôtelière de Lausanne and graduated in 1997, after which she worked at the Intercontinental Paris and then did a five-year stint at Prince de Galles until 2005. She opened Liza Paris in the same year and launched her second restaurant, Liza Beirut, in 2013. This was followed by a pop-up concept in 2014, located in Galeries Lafayette, named Café Libanais. Her most recent project is an online delivery platform launched in Paris three months ago, titled Liza chez vous.
