Ireland's Kitchen Hero comes full circle this evening as he heads back to the capital for the last in the current series of his cookery capers. Donal will be setting up his stall down by the banks of the Liffey for the Dublin Docklands Festival and serving up some seriously scrumptious treats for all. There'll be blue cheese beef sliders for the meat enthusiasts, Pad Thai for those who prefer something more exotic, and some salted peanut caramel mud pie to satisfy any sweet tooth.
