We stayed at the LINQ and was looking for breakfast food. We needed a quick breakfast before heading out for our day club, and something hearty from drinking the night before and more drinking throughout the day. Nook was convenient, since it was at the corner of the elevators as we came down from our hotel room. Nook serves salads, sandwiches, coffee, pastries, and bottled drinks.
I ordered a breakfast bagel with sausage. The bagel was huge! The bagel was about $5-$6 and it was pretty decent.
My only complaint is that our order took a while to come out.
