2 of interest in Youghal
Ahearnes
Aside from great food and a good place to stay the always have a few decent whiskeys, the Old IDL plinth with Bushmills etc, and maybe a dozen Scotch single malts. And a Dungourney, which is handy if you have a bottle and don't want to open it to taste it.
The Nook
Not a huge selection for sale but a few decent bottles, including Greenspot from time to time.
Of most interest is the display cabinet with a lot of very old Tullamore and Midleton (full) bottles along with a few old Powers, Jamesons, Redbreasts etc.
