I used to pop in there when it was Oddbins too - it was the only place I knew of that consisently stocked Deuchars IPA.
I've been into the new shop but I must echo the comments of the original poster: The prices seemed to be very much on the high side, particularly for the Irish stuff (Dungarvan jumped out at me in particular, from what I can recall).
On the one hand I'm delighted to see the range on offer and another venue for the sale of Craft Beer, but if I am dead honest the prices would have me travelling to other locations in South Dublin unless I lived right in Blackrock village.
