This place is way overpriced for a grab and go restaurant, but I guess that's to be expected in a hotel. I ordered an Americano, and it tasted like really really weak coffee, almost like if you made it at home and accidentally used double the water. Although if you did that at home, you would just throw it away and make real coffee, whereas at Vdara, you'll pay $5. A friend who ordered a latte had the same experience.
The bagel was about the quality of Lender's, and they give you a tiny, prepackaged Philadelphia cream cheese to go on it. I could live with having a crappy bagel in the morning, but the espresso drinks were really unforgivable.
For existing and having edible bagels that don't cause food poisoning, I would give the cafe two stars, but because it's inside Vdara (see my review for the hotel), I have to dock a star, because I wouldn't recommend that anyone enter this establishment ever.
