The venue was outstanding for my 45th birthday party! The drinks are excellent and the food worked well. Ross, Stef and the entire team worked seamlessly to give me an outstanding night. I really loved it!
This venue was impeccable! I celebrated my 30th here, had a funeral theme, the staff were so helpful with the setup, the food was amazing, they had a little cloakroom and mic setup. They were super chill with the dramatics that I had on and I would definitely host another event here again.
The venue was excellent, really spacious and perfect location. Food portion was really good as well. The staff is really helpful, our bartender was helpful. Claire checked on me few times a night to make sure our night was going good.
Hosted my 30th birthday at HDN. From start to finish the staff were attentive, welcoming and on point the whole evening. The venue itself its excellent - private space with great facilities such as cloakroom and the sound system/DJ decks. All of my guests loved it and so did I. Highly recommend this space.
The staff were really friendly and accommodating. The room was really clean and we had more than enough space for the party. We had a really great time!
The venue was awesome, the staff were so helpful and lovely, and the catering was delicious. Myself and my guests were so impressed with the upstairs function room.
Just fantastic all round. Used the upstairs room and very happy with it. Staff were fantastic - thank you to the lady on the bar who was excellent.
Great venue and great location. Venue allowed us to have our own decorations which was nice. Great service at the bar.
