You are not scared of being 60 meters below ground?! Then you must visit Bunker 42 at Taganskaya metro. It is a great trip to a cold war era, but we wouldn’t recommend it for kids. You have to book tour in advance and tours are in English and Russian ( tel 8 499 375-21-25). although Russian tour is longer so if you want to work on your Russian, we recommend you try it. Only you may have some issues if you don’t understand when to stop filming??. Luckily, we all came out of the bunker in the end! And if you are hungry you can try the restaurant too, food is great.
