Try Russian beer VASILEOSYROVSKOE TEMNOE - reminds GUINNESS (oh never can be the same but still) yummy yummy!!!
This beer is not well-known and it is easy to find - only in a few bars and in a few shops but it's GOOOD! And there's a shop very near to the hostel where you can find it! it calls HOPMAH (near Oktyabrskaya hotel). How to get there you can see at the map below.
