It isn’t just bars and pubs that are in on the holiday action. O’Sheas, the Irish-themed casino at the Linq Hotel & Casino, will be throwing its largest St. Patrick’s Day celebration ever this year. O’Sheas’ mascot, Mr. Lucky, will parade through the Linq promenade and Guinness will even be giving away a trip to Ireland at the event, so don’t forget your four-leaf clover!
