We had $50 of Food & Beverage credit to kill at the Vdara and Market Cafe was one of the few choices.  My tuna melt was delicious and my bf's egg, cheese, and bacon bagel was not.  These items took 35 minutes to come out of the kitchen, which is pretty ridiculous.  We also ordered some tea, coffee, juice, and desserts to hit our $50 mark.  Apparently pre-packaged items (like salami, ice cream, or canned beverages) do not count.
