This is the west valley's answer to Rula Bula, it is owned by the same people that own Rula Bula. This place has a thatched roof and looks like an Irish building in the middle of an upper middle class shopping center. Its a free standing building and is quite impressive with the style and scale of the place.
The interior (and supposedly the exterior) were all made in Ireland and transported to Arizona for the bar. Sound inefficient but I guess the way you get an "authentic" irish bar in the west valley.
The beer selection is OK, not great but they have what you would expect from an Irish pub, Guinness, Smithwicks, with a couple of craft ales from western US breweries. I did not notice any casks on the menu or at the bar.
Food was good, all Irish inspired cuisine. I cannot comment on the authenticity of the food because I've never been to Irelane. Its a cute place with some decent beer and good food. If you love all things Irish, check it out.
