This is a new word and, unfortunately, there is no unique and uniform translation. I think, Philip has misunderstood the meaning of this word. Destination Restaurants refer to a kind of restaurants of which the chefs and dishes are absolutely first-class that is worth your travelling solely to taste, rather than those booked in advance when you go for a journey nearby. The word 'destination' here means that the restaurant itself is worthy of a journey. Therefore, I suggest that it could be roughly translated into 专食旅行目标餐厅 or 专食旅行目的地餐厅.

招牌餐厅？明星餐厅？顶级餐厅？这些都可能是destinationrestaurants， destination restaurant 是一些预先就预订，或者是计划好要去吃饭的饭店。主要是用于旅游参观的时候使用。就像我们在中国去一个地方旅游，导游预先已经给你联系好的饭店，就可成为destination restaurant，没有翻译过来呢，你可以自己试图进行翻译，比如迪斯汀餐馆，黛丝缇娜餐馆，等等吧。

There is no such restaurant by this name. It sounds funny. Or are you reading "A Hitchhiker's Guide To The Galaxy?"
