Tasty food that's not badly priced coupled with cold beers always make for a winning combination. The pretzels and potato cheese are outstanding and not to be missed. Per my wife, the corned beef and cabbage is also top notch.
I've had their fish and chips (a staple for an Irish place) and it's easily some of the best I've ever had. Knowing how good it is can make your decision difficult should you decide to explore more of their menu.
Though I've not had their breakfast, I do find it interesting that they offer it.
Murphy's Law/Irish Republic is a can't miss spot in Downtown Chandler, for sure.
