Sure, it looks like it's the place where Hana and her band play, I mean that right there in that place Mina meets August and seeing that he is interested in meeting his daughter's friend maybe, maybe! Mina is interested in seeing the club where Hana and Edwin work, so probably August will give Mina a special invitation to see the club.
It will certainly be very fun and interesting to see how Mina will react when she discovers what Killian, Edwin and Hana have been doing all this time in their "job"
