B_knotty,
The list is too long to mention, i found Moscow amazing and bleak at the same time, but i did all my visits there in winter.
I found the Metro unreal, neve come across such a vast and interesting place. Each Station is a work of art.
Tverskaya ulitsia and arbat are worth a visit even if they are considered touristi.
Just wait till you see Red square for the first time.....its gonna knock you for six!!
