Tucked away down a side street next to Stephen's Green, I only became aware of this art gallery when I went to a "Hennessey Lost Friday" event hosted here (using the gallery as a space to give artist tours as well as cocktail lessons, art work and music).
The first thing you find on entering is the cafe - a smallish space, with a relatively simple, yet tasty menu (the meatballs were delicious).
Then into the Academy, where there are a set of different rooms hosting different artwork. I was lucky enough to get a tour of one of the current exhibitions "Foggy Dew" from the artist (and current RHA President) Mick O'Dea, which further enhanced the experience (head there soon to see his contribution to the centenary celebrations).
With no admission fee and changing exhibitions, worth a look in if you are in town
