Welcome to Just Answer
I am a Solicitor and will assist you.
I think that this has been drafted by your barrister very well.
I think the wording is not particularly binding to you. I say this because the words 'sensitive and reasonable' to me do not imply that you are to strictly adhere to purchasing halal food.
I would interpret this as you being open to offering different options - say perhaps a vegetarian option if halal is not available to you. You could go so far as to say that if you were having Christmas dinner as a family and the meat was not halal - this would not breach.
If, however, the only meal you ever offered was hamburgers then the other party might argue a breach.
Do however also note that if this is in the recordings section rather than the order section - then it is not enforceable in any event as a breach.
Positive feedback is gratefully received
which is least binding statement 'as far as possible' or 'so far as is reasonable'?
