I picked this book up a couple of weeks ago and at £12.99 I think it was a great buy. For a student like me or for professionals it has details of good exhibitions, architectural gems, retail fitouts and restaurant wonders that should be visited. And the fact that it lasts for two years makes it even more useful, well worth the investment.
