I haven't got any experience as a receptionist in a restaurant but I was a waitress, shall I apply?

I want to apply to a 5* restaurant in Central London. They need someone with good telephone manner and managing bookings. I worked in Hilton hotel as a food and beverage istant but have never done any telephone skills and managing books. How can I say it in my cover letter, trying to link it with my restaurant experience at Hilton?
