Hi Ballyman,
We've lived in Sallins since 97 and love it, there is no real supermarket as such, nearest is naas or clane, clane easier to get to as traffic in naas can be crap, 3 pubs in village, all ok except the big one!! Ther are plans for supermarket, hotel on Millbanks site and the new hotel will open soon in Kerdiffstown. Traffiic in village can be crap from 5-6.30 in evening but it moves.
