This is a low key relaxing 24 hour whiskey bar right on the casino floor. They have their own selections of Four Roses, Woodford Reserve, and Jack Daniel's single barrel so they take their selections seriously. I tried one of their Woodford cocktails and had a seat on a very comfortable leather couch and relaxed. They have table games with crazy high minimums in here but I didn't see anyone playing them and one guy spent a few minutes awkwardly trying to flirt with the dealer.
This place is a hidden gem in the MGM Grand.
