The place is a half storey down, cozy, and packed with people and great music. There are special events around the weekend: karaoke, live music, etc. There often take place concerts (which are paid, at least some of them), so it is good to ask what is on the day and what is the ticket price. It's a great pub to watch football games too.
It is one of the few places in Sibiu city center with a good vibe at night and many concerts happening. Prices are more than decent considering the placement of the pub and also the food is really nice if you want to eat there on day time (they might not have the fastest serving time but that is only because of the quite small number of staff).
Local bands perform there and some of them are really good, maybe you catch Onenightstand (very popular local band in Romania).
