As a regular in the ETA Lounge I'm probably biased but I've always loved the decor and the staff. On the weekend they have a DJ and a couple go-go dancers. Sometimes it's a little slow but it's always a great place to just have a drink and sit with friends. The gambling ain't terrible. Too bad there isn't food served at the bar but they allow you to bring some in from the food court if you want. They make some great drinks overall. Some may experience a touchy staff person or two and I have first-hand witnessed it. Generally speaking if you run into someone in service that's annoyed then don't tip and move on. Unfortunately sometimes people like to exchange words and that works two ways.
But if you get a chance to check out the Lounge I recommend it.
