This. Have used Justpark several times and it's always been excellent.
Good but deathly, deathly quiet the night I went there. Also assumed there might be somewhere selling drink nearby (there isn't) and I could catch a cab back easily (I couldn't - had to call)
Also the street that Brewdog is on has enough unsavory characters in the evenings to perturb me and I work in the roughest part of Dublin (and have been to Birmingham repeatedly)
