I have tried chocolate martinis all over Vegas. My faves have been at the Wynn and the iBar at the Rio until I discovered the Chocolate Bar at New York, NY. I had Death By Chocolate and the Reeses Martinis. Not only are they tasty and strong but they also cost less. Only $12 each as opposed to $16 at the Wynn and $14 at the iBar. My only gripe would be that the bartender does not fill them up as much as the other places, but if you ask nicely when ordering, she will take care of you. I was told that it just opened last August. Can't wait to go back!
