"Secret" drinks or house specialties up and down the strip?

Along the strip, tell me about some secret/special drinks to any particular bar where you like to play VP.

If it is neither a secret, nor a particular house specialty, but you think a particular bar/casino has the best *whatever* drink, feel free to mention that as well.
Examples:
Bellagio has a signature cocktail that I've tried. It was good, but a little too sweet for me.
A bored waitress in Cosmo high limit made us frozen strawberry margaritas.
I know quite a few here on the board get vespers at Cosmo.
Pretty much anything from Whiskey Down at MGM is great.

And...go

 

An easy one:

Cosmo->Verbena (at the Chandelier bar)

 

Thanks GChrome. I always forget about that one! I think my wife would love it based on the ingredients, except for the lemongrass syrup. How strong does the lemongrass flavor come through?

 

The Peppermill, try their scorpion - 64oz signature cocktail.

Probably not comped...but really good.

 

Haha, don't worry about the flavor of the actual drink, just make sure you chew the flower bud thoroughly.

 

Whiskey Down - Fire in the Hole

It is still on their online menu but won't show up on any of the menus at the bar. Not all the bartenders know that they can still make it but they keep the Greg Goose hidden under one of the bars.

Fire in the Hole
Grey Goose La Poire, Fireball Cinnamon Whiskey,
Fresh Lemon Juice, Rock Candy Syrup

 

So it makes your mouth numb. Does it have the same effect on your throat? I'm asking for my wife :evillaugh

 

at the Nacho Daddy restaurant in downtown you can get a shot with a real scorpion in it

oh but that's not on the strip I guess

 

Wow, that sounds good. I'm getting thirsty.

 

WHAT?!!!!

Where and how much?!

 

That sounds...rather awful! I imagine you need a few shots of tequila before and after? Have you done it?

 

It is very good and goes down way too quickly. Watch out, they will catch you off guard.
