It's a pity that many people only go to Kremlin or Red Square when they come to Moscow. I spent there 5 days and I loved the city. And the metro stations are really beautiful! The Russian cuisine is delicious and there are many healthy meals so it's good that you mention it too.
I didn't know about the mosque! I will definitely go to Moscow again and then I'll check it out :)
Thank you for sharing and congratulations on your curie vote!
