I suggest you to drink local vodka and not famous trademarks vodka in Russia. As you can be sure to drink vodka when you buy a local one and at the same time you aren't sure anymore buying something similar to famous trademark,
In Siberia it is a tradition to go to russkaya banya or russian sauna like in all russian regions. The interesting thing that in the local swimming pool it is also sauna and you before and during swimming can go to sauna to heat your body and to drink a cup of tea during your swimming exercises. I like it and suggest it to everybody.
