Ferguson's, the Hawaii recommendation, is a great (small) bar in downtown Honolulu but there's nothing really amazing about their Irish food selection. On the other hand, there's really no exceptional Irish food anywhere in Hawaii so I guess they deserve the nod as much as anyone else.
As an aside, one of the best parties I ever attended was John Ferguson's wake held at Murphy's, the best known Irish bar in the area (and about two blocks from Ferguson's). Shortly thereafter, (Don) Murphy and the owners of JJ Dolan's (yet another Irish bar a few blocks away but one that specializes in pizza) bought Ferguson's from John's widow, upgraded the build, and still run it.
