Things have certainly slipped. Last year we went regularly for the Sunday Carvery and the place was packed out, food very good and "help yourself style" which suits me as I'm a Coeliac so need to be careful what I eat.
This year we went earlier in the year with friends and it was now Sunday lunch served ready on the plate, food quality not so good, we thought maybe because it was early in the year. However we thought we'd give it another try last Sunday, still on the served on the plate job and food quality pretty awful.
We did get good service from our American waiter but maybe that was because we were the only 3 eating out of the 8 or so people there. Such a shame as it's a lovely setting and used to be so good. We won't be going back.
