Despite the fact that your readers are of above average intelligence, I believe that you have over-estimated their ability to actually find Necca Shibuya (see article). Perhaps in the future you should provide either the URL (as Internet-based businesses is your primary coverage) or a basic map on how to actually arrive at the given place that you have reviewed. For the benefit of the other people hopelessly wondering the back streets of Shibuya, the URL is www.interpia.ne.jp and the phone number is 03-5728-2561.
No Longer Lost,
(Editor's reply: We did include the URL, but perhaps we could have made it a bit more prominent. Thanks for your note.)
