Lady Stardust: Outdoor yoga, cycling, picnic gathering, relax reading a book or drawing are some of the activities I personally use to enjoy. And whichever, Fitzgerald park will provide the vibe you are looking for.
Aisling Prendergast: Lovely smoking area, fire in one part, fairy lights all over. Good spot for a date or casual drinks with friends. La Tana Pizzeria will happily deliver here also.
