UPDATE: The Ritz-Carlton at the Herzliya Marina is now open. The Ritz has a kosher restaurant location within. Other luxury hotels in Israel (Waldorf-Astoria in Jerusalem and a W Hotel in Jaffa), are open or opening soon.
The Ritz Carlton has announced that they will be opening up their first resort in Israel, in Herzliya, an exclusive residential seafront town north of Tel Aviv, by the end of 2013. As Israel advances technologically, Herzliya (as an extension of Tel Aviv) could be described as the Israeli version of Silicon Valley (or Silicon Wadi as it is known locally), making it a popular destination for business travelers from around the world.
