Irene Diary Farm Restaurant - disappointing!

I have visited this restaurant on many occasions - the setting is something to enjoy. However, the attitude and level of service have declined to such an extent that I shall not visit again. For example, there is a "Smoked Salmon on Sourdough" with additions) on the menu which I duly ordered. The waiter told me to consider two other salmon dishes (salmon fish cakes and seared salmon), but I had needed something light and smoked salmon would do the trick. Wen the dish arrived it was obvious that it was not smoked salmon at all, but rather some seared salmon cut into strips and smothered in rocket. The waiter refused to take the dish back and my lunch partner kindly agreed to take it as a takeaway. No too hungry I thought I shall do without lunch, but will mention the fact that I received something I did not order on the comments sheet included with the bill. The manager then duly arrived, read the comment and told me "Sorry, it is an error on the menu" and that was that!! No acceptance of any responsibility or offer to rectify the situation. Very disappointing!!
