Being vegan, me and my wife ordered Earth Burger (veggie) and to be honest this was the worst burger we have ever eaten. $15 for such a crap. On top of that they won't even serve you any sides. Serving size is also small. I am not going to this place again ever !
If you want some really awesome burger, try Veggie Burger in Grand Luxe Cafe in Venetian or Palazzo. You will love it.
