"We dined at The GBR last night as a party of six. It would be fair to say that the GBR has one of the least imaginative menu's in mayfair and probably makes the Pall Mall clubs look innovative.. Upon arrival we were told 1. They only had 4 steaks left 2. They had no duck 3. They had no mussels Service was geologically slow and rude, the waiter serving drinks seemed to think that each time we ordered a bottle of water he had to immediately empty it into the water glasses on the table whether people were drinking or not. We ordered a £90 bottle of wine, this was not available and we were told the only available was a very mediocre Malbec at £30. We arrived at 7.30 and main courses were not served until 9pm after multiple chases. I ordered a monkfish starter, which came in the greasiest batter known to man and a large portion of fries, a very strange starter, main course was a lamb dish, to be fair it tasted nice but was at best tepid. None of us could face desert as we were all desperate to leave the restaurant as the service was so poor and the food so disappointing. I honestly think this was the worst dining experience I've had in London this year. AVOID."
