Starting on Friday 23rd February the Night Overground service from New Cross Gate to Dalston Junction will be extended to Canonbury and Highbury & Islington. At Highbury passengers can catch a Night Tube on the Victoria Line and change at Finsbury Park onto the Piccadilly Line. To reach Palmers Green is then just a matter of taking the N29 from Wood Green - they run every 7-8 minutes and the journey time in the early hours is very short.
