I was in today. Service very, very poor initially. No one on the terrace when we got there so had to go to bar for drinks. Ignored at the bar while the barman was sorting some cans out, when I finally got his attention and asked for some LPGS I was told they just had a delivery so no chilled LPGS. This was around 1200 - he did say the Canard Duchene was the best champagne they offered. (!!!).
Tried the BA100 English sparkling wine, fine but not amazing. Friend went back and by then LPGS was on which was a big improvement.
Fortunately after that the lady working on the terrace was on the ball and kept us well looked after until we left for our flight, though she was run off her feet as I think people realised she was the only person who actually was bothered.
So very definitely not the CCR’s finest hour.
