Venus Fort from name to concept has always puzzled me so I am right here with you on that call. To describe Roppongi Hills as tacky however would just be inaccurate and this forum does not need such inaccuracies, thanks.
I gotta put smilies on these things or some folks take them seriously! Humor, however misguided, was intended, honest. Along those lines, let me add that I rate the overall restaurant selection at Roppongi Hills as substantially superior to Tokyo Midtown.
