Honestly- very disappointed.
The waited was awesome, but that's about all I can say was exceptional.
Firstly- the "immediate service guacamole"- can taste the processing of it, it's bland, fake tasting and definitely not freshly made- a good fresh guacamole takes 5-7 minutes to make properly. This tasted like it was scooped out of a plastic tub from the grocery store.
The mahi mahi tacos I ordered were ok- nothing to get excited about.
My wife ordered steak fajitas- those were actually pretty darn good, very tasty, but had lots of fluid in the skillet with it so the vegetables got soggy after a couple minutes. Also, their tortillas were not held in a steam pot so wishing a minute of removing from the wrapper they got very hard.
Honestly, for being inside a nice casino in Summerlin, it was a very big disappointment.
