Our event itself went very well, and I would like to begin by recognising Ash, the bar manager, and her team. They were excellent throughout the evening. Had they been responsible for the overall booking process, we would gladly return for future family events.
It was a great night! Rachel was fantastic behind the bar and the DJ delivered perfectly on the music brief! The recent renovation looks great as well.
Good communication and advice from the Venue Great food choices and cocktails Well presented Venue Accomodating to decorating the room with balloons etc You can play your own music Reasonable minimum spend value
The communication was really wonderful, I threw my husband a 40th birthday, it was so good! The venue is perfect, not too big, accommodating, the bar staff were lovely and catered to anything I wanted as best they could. Can’t praise the venue enough and will be recommending to anyones who asks
(We had the PARTNERS room): Everyone had a great time, lovely food (good selection for vegans and vegetarians), a good selection of drinks. We were able to play our music quite loud & enjoy the little dance floor we’ve created. Pub is beautiful as well. Thank you so so much. (Great communication too).
The venue was private enough for our party size. Staff were very friendly and the pre-booking member of staff, Charlotte was very helpful and really accommodated to our brief.
The bar staff were fantastic and offered to do all they could to help. They made everything super easy and straightforward! The space was perfect.
Really accommodating, allowed us to decorate the venue as we wished. DJ which was booked for us was great. The food was excellent and amounts catered for were spot on. Staff very courteous and looked after us well.
