The 80-capacity Private Lounge Bar has its own bar complete with your own cocktail bartender, leopard print fireplace, botanical sky light, secret Instagram corner and also private access to our beautiful shared garden.
Since you will have your own private bartender, we can organise the cocktail making too, if there is anything specific you would like let's arrange it!
The lounge is perfect for those looking for their own private space and provided it is not hired privately, we'd also be able to offer a space in our adjacent garden.

It is the perfect place for dinners and parties alike.

Super cool venue, worked great for our shoot. Host was friendly, accommodating, and easy to work with. We had full run of the space which was ideal.
Parking is limited but manageable

The team looked after us well after getting their attention on arrival. They set up the speaker for us after some teething issues and the bar staff provided on demand. Everyone had a great time and good service for drinks and food. Didn’t have to remind or worry about catering, they came out at the agreed time and served some tasty nibbles.
Nothing of note. I thought the chipolata canapé was going to be a bit better.

Staff; peter and the bar staff on the evening Hospitality Drinks and food were good Generally everyone who came enjoyed themselves therefore i’m satisfied
Slight miscommunication in the arrangement we thought that because we hadn’t booked the DJ we were going to be given the speaker for the night but it had to to also be pre arranged which it wasn’t so first half of the night was generic bar music that had everyone sat down not really vibing but this was quickly solved when peter compromised and offered us the speaker and allowed us to play our music which then livened up the evening.

No, bookings are completely free, without any minimum spends.
No. We would advise either hiring a DJ or having the DJ in the main room relay into the room, as our DJ in the main room would not fit with you having a speaker.
External entertainment would need to be reviewed by the venue beforehand.
Yes, candles and sparklers are permitted.
The venue has microphones, PA equipment, screen and projector access, speakers suitable for music and announcements, and a setup that can transition into a dance floor later in the evening.
