The first requirement to enter in Smolna is to be dressed completely in black. Smolna is a dark nightclub so it is logical that they make their clients dress in this color. Once you have dressed in the perfect look, it’s time to make an effort by your part.
Learn by heart the DJ that plays that night. The doormen of the disco are going to ask you who is the person behind the DJ table, if you do not know what to answer they will invite you to leave the queue and go outside. You can check the DJ that plays every night on his official page: Smolna38.com
After this you can go to the club. However this is not a guarantee of success. The last and most important factor is comming.
To enter into Smolna you have to go in groups of four people maximum. I said maximum because even being 4 they can kick you out too. I went with 3 friends, there were 4 of us and they let us pass. This is because two of them were Polish and already knew how to talk to the doorman. However, our half of the group stayed out because they were not allowed to pass. They were 4 people, 3 boys and a girl. Even knowing the DJ, dressed in black and all, they did not enter.
But take it easy, relax and don’t be nervous. Even if you do not enter you have the pawiloni area next to you as an alternative.
