Here is a brief look at the very recent state of Diablo's Cantina.
The south end of The Monte Carlo has been changed from a picturesque staircase into Diablo's Cantina which opens September 2007.
Diablo's Cantina will have sultry senoritas and roaming tequilla vixens.
They were running a website which had some info, but now that website refers to the parent company of Diablo's, so I am not presenting that link.

From what I have read and seen of this place, it looks like it will be rather cool (hot).
The Monte Carlo - Diablo's Cantina in the front, McDonalds in the back, no self parking garage at the present moment.
Perhaps Diablo's will be the beginning of a good turn of decisions for The Monte Carlo.
