O'Sheas is a fun casual pub-casino inside the Linq. I stopped in a few times to watch beer pong, listen to music, & people watch. It was never overcrowded, but never empty either.
I really liked the late afternoon band that set up. They sounded good, not too loud, & their playlist of cover songs held my interest.
People walked through O'Sheas from the Linq to the Promenade & vice versa. Some liked the vibe & stayed for awhile.
