Although we have a huge Grand Lux in Houston, I hardly ever go there because it's so busy. It turns out they all are! I went to this Grand Lux because it was in my hotel. We ate at this place several times and although it was super busy, we were always seated within 10-15 minutes. They have a lot of variety so you don't always have to order the same thing. I thought the food was Good and the drinks were pretty awesome.
Don't forget there is another Grand Lux at the Palazzo, so if this one is packed... just walk to the other side of the Casino and enjoy your meal!
