Be the first to add a review to the Rainbow Casino Hotel. If you go to the Rainbow on the weekend, you will need to plan ahead for your meal. There is usually a wait for up to an hour prior to being seated. Even with the wait, the dining experience is well worth it. My family usually plans to go play for a while as we wait for our table and things work out just fine. Casinos Rainbow Casino is located in 1045 Wendover Blvd, 89883, West Wendover, USA. Everyday Promotions at The Rainbow Casino sign weighs 22,000 pounds and took YESCO 4,400 hours to fabricate and install. The Club JewelTM card is available to all players over the age of 21, to get yours, just head over to the cage at either casino and a team member will be happy to assist you. The “Rainbow” letters are RGB LED and dynamically illuminated in the colors of the rainbow.
