Last July the story was: "Here comes the Jackdaw jazz cafe." But the venture has lasted less than a year. This is a shame, just as the closure of Maeve's Kitchen is shame. Now there are two empty spaces where examples of local gentrification had been, once again raising questions about why some manifestations of the "new Clapton" have taken root and others haven't. The Jackdaw seemed nice enough, but did it over-estimate the Dalstonisation of this neck of the woods?
