Not impressed.  There are so many great burger places in Vegas, this unfortunately is not one of them.  We sat at our table for 10-15 minutes before being acknowledeged.  The menu is basically a la carte and completley overpriced even for Vegas standards. If you want a plain burger, fries, and a drink its almost 20 bucks.  The food took forever despite the restaurant only being half full and about 8-10 guys working in the exposed kitchen.  Told our server if she could put a rush in the order that would be great considering we had to catch a show and we had already waited insanely long, she gave me attitude and said everything is made to order so theres nothing she can do, rather than just saying \""ok sir\"" to shut me up, which I would have preferred.  She then said she was leaving cause her shift was over and someone else would take care of us (no problem).  He checked on us once, and gave us the bill.  There are a lot better options for a place to eat and I suggest finding one of them (unfortunately mirage really does not have that great of options).
