In brief, it was very good, but I wasn't wowed by it. My expectations were set too high because of Gordon Ramsay's name attached to it.
The ambiance, the atmosphere and the decor were absolutely gorgeous. The service was impeccable, although some of the staff were having a bit too much fun at the bar, which was a bit distracting. If I was basing my review solely on these factors, I would give it 4 and a half stars.
The food was good, not great, but very good. I had the English Ale Onion Soup, which I liked, but thought it lacked. The onions were gorgeous, the cheddar crustinis were good, but the broth didn't have it. My main was the filet platter. The steak was nice, the pork belly was a bit boring and the shrimp were not hot enough. My friends had similar complaints and compliments.
All in all, not a bad choice, just not as good as I would have expected!
