My wife came up to town after my exam as I had booked her a surprise lunch for her birthday. We went to Clarke's, a place she had always wanted to go to. She wasn't disappointed - really fresh food nicely presented and all very much in season. OK it was full of "ladies who lunch" given the location in Notting Hill/Kensington but that didn't matter to us.
The wine list features Californian wine. Unfortunately they only did 1 red and 1 white from the US by the glass but I wasn't sorry I tried them. A lovely buttery, tropical fruit '05 Chardonnay from Au Bon Climat and a plummy, soft, silky Merlot from Havens Vineyard. It was a '97 which puzzled me but it tasted as though it could still last another few years.
Although the focus obviously was to treat my wife it was a rather nice way to spend a couple of hours after the exam.
