First, tell yourself that “too much new art in London looks like high-falutin’ tchotchkes created for investors with at least one eye on the auctions,” and that what with the Current Economic Climate the faint stink of desperation is only going to make things worse before they have a chance to get better.
Then, get a friend to go bunk into the openings of both art fairs and get loaded on the free drinks, before reporting back to you the next day that pretty much everything she saw there confirmed your prejudices.
