I guess it is relatively new, and not many people heard about this cool place, and this might be the only explanation why this lovely bar wasn’t full on a Friday night. It is not a big place, and it can contain double amount of people if they would organize it in a different way, but then it will lose it magic.
There is enough space to privacy, and to be able to hear the person you are with. I saw few couples on their first date, and I thought to myself that there is no better place to meet someone new for the first time. You have private places, or a bar seat. I would choose the sofa.
I am sure that in few months, after more people will discover the place, I will not find a spot to seat that easily anymore.
