Out in the extremely lovely Enniskerry is Powerscourt House and gardens. The views and house alone are worth going for. What makes it even more attractive is that there's an avoca restaurant there :). The restaurant runs nearly the whole length of the back of the house. Several huge bay windows run the whole way down the restaurant. I wasn't lucky enough to get one of those tables. There's also a very large patio out the back with unreal views.
Blue skies make me happy.
I got a vegetarian Pastie which was AMAZING!
