It seems that Dum Laga Ke Haishaa in Kolkata refers to a club or an event space, but there isn't much detailed information readily available about it in prominent sources. It's possible that it's a new establishment, a themed space, or a smaller local club that may not have widespread recognition outside its immediate community.

Given that the name Dum Laga Ke Haishaa is famously associated with a Bollywood movie, it's possible that the venue uses this name to evoke a lively, fun, and energetic atmosphere, perhaps resembling the movie's theme of perseverance and humor.

If you're looking for specifics about the club's offerings, atmosphere, events, or location, I recommend checking local directories, social media pages, or visiting review platforms like Zomato, Justdial, or Google Reviews for up-to-date information. You could also try asking locals or people familiar with the nightlife scene in Kolkata for recommendations on what this particular venue offers.
