This is a little gem on the 4th floor of the Venetian inside the Canyon Ranch Spa. We had the English muffin breakfast sandwiches with coffee and the bill was $47, so not for the faint of wallet. That being said, when I am in Vegas I am on vacation and still like to eat healthy and this place fits that bill.
Take the suite elevators (you likely need to be a guest) to the 4th floor and follow one of the guest suite hallways down to the Canyon Ranch Spa and you'll see it on the left as you enter.
I knocked one star off for price - I found it to be a tad over priced, even for Vegas.
