I went here all three mornings of my stay in Vegas. It was a grab and go kind of thing, but I grabbed breakfast here every morning before I logged on to work for a few hours in my hotel room.
Breakfast is very affordable here (for Vegas). I usually got the two eggs, fresh fruit (no additional charge) and bread with espresso on ice. I couldn't call ahead for pickup, but the food was always made and brought out promptly. Definitely recommend this place as a great grab and go spot in the AM post too much drinking the night before.
