Go elsewhere. The Rio is not exactly known for their food and this is no exception, but will set you back at least $50.
Here are the issues.
The host didn't get our jokes. She was kind of a stick in the mud.
There is a holding area for the elevator. There was literally what looked like a gurney for moving people around and weird "voodoo" like decorations on the walls. We got in the elevator of horrors, which was not air conditioned. The view outside was great, but not at 140 F.
When we got into the restaurant, there was a weird lion/leopard/Africa them to the chairs, but a decidedly French/American menu. We had a nice view.
Our server forgot my order of truffle mac and cheese and there weren't really truffles in it (they faked out on me when they finally brought it). My lobster bisque had a skin on it by the time it came out, my sidecar was average.
One saving grace was the basket of bread brought out. It had the parmesan flat crisps and they were quite good.
We were also charged for water. Tap water.
If you want a view, hit this up at night for the club. It seems better suited to that than as a restaurant.
