Basically all free drinks, snacks, and lounge area available for Caesars diamond members and one guest, so the high rating reflects that.
4pm-6pm they serve just a few hot food options that are pretty decent. Real good cucumber salad and chips and dips. Desserts are good.
Fast service with lots of refills and drink options, my favorite plain ice tea in lemon is spot on. :)
Thanks Rio and Caesars, I'll be back often.
