Christmas Party · 100 guests

We had a fantastic time at Marquis Cornwallis for our Christmas party. We had around 80 guests, which felt like the most we would want in the space, it was very full but it worked. The staff were fantastic and the food was great, we'd definitely love to be back!
The advert said the space would hold 100 but we had 80 and that felt as full as would be comfortable. Not a complaint, just a comment for future.

The room is lovely and the staff efficient.
Our party started at 630pm and we were not told that another party ended at 630pm... so we arrived a little early, as Id indicated we would to see everything was OK, and the other party was still underway. Our guests were arriving and the staff were still clearing away. It did happen quite quickly but it was a surprise to say the least.

Lots of space, and it was easy to set up the projector. The staff were attentive and supportive as well
Would have been good if we were able to remove some of the chairs and tables, from the space, but we made it work!

30th Birthday Party · 60 guests
· February 2026
· The Drawing Room
Overall it was an excellent service all evening. Our bar staff was extremely helpful with all of our requests such as dimming lights, aiding in our set up of the room etc. and dealing with quite a crowded room. We really appreciate it and my mum and I had a great time overall so thank you!
If a slight tweak would just be that it wasn't massively clear when the bar staff would clock in from and so at the beginning of the event, the bar was left unattended for a while and we came downstairs 2-3 times to ask but once started, it all was fine!

- Natasha L. rated it 4.4/5 stars
'It was a great space for a birthday party - it felt spacious, was useful to have a private bar and aircon if it’s a hotter day. The team were very helpful and quick to respond to any questions in the lead up and on the night and happy for me to send cake and decorations to be delivered there which was so helpful. Food and drinks were all very nice and all went smoothly too' - Maddy S. rated it 4.4/5 stars

Our bar staff was extremely helpful with all of our requests such as dimming lights, aiding in our set up of the room etc. and dealing with quite a crowded room.

'The Marquis Cornwallis is a lovely venue and had been decorated beautifully for Christmas. The food was of a good quality and the staff were very helpful, both at the event and in planning it.' - Angharad G. rated it 5/5 stars
'I liked how versatile, beautifully maintained, and decorated the drawing room was, it was a perfect size for our party of 50 with plenty of natural light, and a bar of our own in the private room went down well. The food was great, wide menu choice for people with allergens, plate was well presented and a good portion size, served hot. The bar and waiting staff were attentive and helpful with a special mention and thanks to Kieran who was brilliant! Thanks'
