O'Sheas, Casino at The Linq, Las Vegas Strip, United States

O'Sheas is a gaming establishment within The Linq Hotel on the Las Vegas Strip, offering blackjack, roulette, and slot machine tables. The space is divided into multiple sections, including three distinct bar areas with an outdoor section overlooking the Linq Promenade.

Hilton Nevada Corporation broke ground on O'Sheas on September 7, 1988, on land used for tour-bus parking, and the casino opened July 1, 1989, costing $22 million. It closed April 30, 2012, and its seven-story rear parking structure was imploded the next day. O'Sheas reopened December 27, 2013, in a 5,000 sq ft space on the Linq Promenade, connected to the former Imperial Palace casino.

The leprechaun mascot dates to the original 1989 casino; from 2006 Brian Thomas played Lucky, greeting guests and returning in the new location. The bar is known for cheap beer and beer pong, and both sites have drawn crowds for St. Patrick's Day. In 2006 Vince Neil of Mötley Crüe opened a tattoo parlour whose glass room faced the Strip.

The casino operates daily from 10:15 AM until 6:00 AM and is located within The Linq Hotel on Las Vegas Boulevard. Visitors can access the gaming and bar areas from multiple hotel entrances, making navigation straightforward.

A leprechaun mascot, originally called Paddy, dates back to the original 1989 casino. From 2006, actor Brian Thomas played Lucky the Leprechaun and mingled with guests, becoming a favourite; he returned in the role at the new Linq Promenade location.
