I went to the opening of Alan Cristea’s extraordinarily smart new gallery on Pall Mall.   I am perhaps the only person who regrets his move southwards because he could, and should, have been the anchor tenant in the renovated Cork Street where he would both have given the new development historical legitimacy and attracted other blue chip tenants.   Suffice it to say that he is part of a move of the art galleries away from Bond Street back towards their historical origins on Pall Mall, not far from where both the Royal Academy and the National Gallery were founded.
