O'Sheas was fun. Cool music to sing along with and bob your head to while playing $10 blackjack at the tables. There were TVs with sports on and beer pong tables in close proximity. There is something for everyone. It was perfect for a late Thursday night arrival. The waitress serving the tables was quick and came around frequently, but I brought down a giant drink from the room, so I was straight! :)
If you are staying at the Linq, this is a cool place to go to. Bathrooms are close by at the flamingo, right across the way. If you need some fresh air, you are about 20 feet from being outside. They also had live music on Friday night and it was really good reggae. I'm not sure I would go way out of my way to come here, but if you are in the area, definitely check it out.
I guess that it helps that I did okay at the tables too...
But overall the vibe was good.
