I have yet to see the Mermaid in the tank , but this is still a very cool little thing to check out if you happen to be at the Silverton(which I was last week).
Located right next to the Mermaid Lounge when you enter the doors at Valet, the tank has plenty of aquatic life within. Many different species of fish and a bunch of sting rays seem to always be moving about.
Also, behind the tank is some Mermaid related artwork, some of which is very cool and all of which are very expensive, if you wish to purchase it!
Of course it is free to check out and you can't beat that!
4 stars.
