Definitely one of the more hidden gems on the Las Vegas Strip. Located between Mandalay Bay and the Luxor hotel this place offers a great atmosphere (mature crowd, live bands), with excellent food.
From my experience overseas, I find there are two types of Irish bars. There are the "meat market" pick up joints that are extremely loud, packed and filthy. Then there are the clean, lively and cozy places like Ri Ra.
Our group was in Ri Ra on a daily basis for either breakfast or pre-drinks and I would strongly recommend it to others who are fans of the Irish Pub Experience.
