Thanks Flowermummy - I'm glad you found the post useful - and I'm also glad to hear that many others have had good experiences of the Bolingbroke.
In this one instance, I didn't, and wanted to share my experience of that on this forum - (as well as emailing them separately, FYI NVHusband) just like many others have done with their experiences - good and bad - of local restaurants/services too.
I think I made it extremely clear what my problem was. Several times.
As I mentioned before they have actually emailed me in response to my original email, apologised and provided a voucher so I hope to try it out in the future.
I can also see they have also now (since) added some new text to their 'kids' page on their website:
"Please note, we welcome well behaved children (and parents) until 8pm. Children under 14 must be accompanied and supervised by a responsible adult at all times."
So well done Bolingbroke for a great response!!!
Also for info daisydaisy - their policy is not to do with licensing laws - it's to do with their simply not wanting to have loads of kids in after a certain time in the evening. This was confirmed by them to me in the email too. I fully respect this policy and am very happy now they have made it much clearer on their website.
