Traveling in August 2019 in Germany, we stopped here. Something reminds us of our outlets around Moscow. Most branded stores are available in Russia, but the assortment here is bigger and better. Some of our products are sold as new items, and there they are already at a discount and a significant price difference than ours. Large parking, cafes, restaurants and a Magdak are available. We were by car, but buses run here from Berlin.
There is a website, you can choose the Russian language:
