What is the equivalent in English for 移步？ Literally, this means striding or walking, but it seems a polite term to urge people to move, e.g., 请移步到餐厅用膳, shall we say "Please walk to the dining room for your meal?" It sounds very awkward, because unless there is more than one mode of movement(as in an airport you can either walk or take a bus to get to the aeroplane), walk should not be mentioned or even stressed here.
In fact, by saying "移步", there is nothing implied here and it's just a polite term. It simply makes sense by removing 移步 from the sentence. 请到餐厅用膳。

Personally, I don't think it's a good usage of 移步 in the context. It's kind of redundant.
