We came here for our 7 year anniversary for a Sunday lunch. It was really quiet so we were lucky to tour the kitchen during our meal. Service was impeccable and food was definitely top notch. Service charge is included in the meal price which makes things easy and it is prepaid upon making the booking so all you have to worry about is the drinks you have on the day/night. Never did we feel the staff were pretentious, something that we've noticed in #1 rated restaurants in countries around the world and kudos for making everyone feel welcome. I know they have a no jeans policy but when we were there, there were a few men that wore jeans. I think so long as it's not the street wear / ripped type then you should be okay, but hey, why not dress up a little seeing as you're in one of the best restaurants in the world! They also gave us two jars of granola to take home and our personalised menu. Would recommend and I am planning on returning for another anniversary!
