In my humble and somewhat besotted opinion the McMullan family run the single best Irish pub in Las Vegas.  Unlike the vast majority of bars in town, this is not a corporate operation run by MBAs from afar.  Instead, the eponymous McMullans are there every day.  Furthermore, they are extremely involved in the community.  Their \"St. Baldrick's\" charity drive raises donations in six figures for children with cancer every year.  McMullan's Pub features all the beverages that you would expect in an Irish joint with the food being a definite step above usual bar fare. (I'm partial to the fish & chips, myself.)  However, the social experience, good music and the \"craic\" is what you go for here and you get a full heaping serving of it on every visit.
