SW is probably my favorite steakhouse in Las Vegas. Everything is beautiful about it (atmosphere/service) and the food is on point. I wish I could elaborate a lot more on what I ordered but it was just a barrage of goodness.
I believe I ordered this:
Chile Rubbed Double Rib Eye (for two)
While this was amazing, I sort of wish I got something more purist like a simple porterhouse or any bone-in cut without fancy spices. Whatever you end up ordering, it'll probably be amazing.
If you're serious about having a great dining experience here, be sure to make a reservation and dress correct. One time I tried to do a walk-in and I was wearing shorts and they weren't having it. You could probably do a walk-in and wait for a table but make sure you're dressed appropriately. If you're trying to get some that night, get a reservation at a table that directly views the artificial waterfall outside.
SW is the truth.
