I was here on opening day and have been a loyal ever since. The Guinness is awesome, poured correctly (very HARD to find in Vegas). It's the only place in LV that actually is an Irish bar and servers Irish food like Irish Breakfast. The food is always great.
The Whiskey menu is amazing. Bartendars are friendly. To respond to an earlier remark...These are not fake Irish accents. They do move here to do this and they are from Ireland. If you've ever visited Boston you know they do the same thing in their pubs, too!
Friday locals get 40% food! You can't beat it! Not Happy Hour specials so if you see a coupon, use it!
