Located inside the JW Desert Ridge, the food at twenty6 is overpriced as you would expect for a hotel bar, but the happy hour (2-5pm daily) is pretty good. During happy hour, they have $6 margaritas (too sweet), sangria, wine, and beer. The deviled eggs ($8 during happy hour) were very good, but still a little pricey. You're really paying for the nice seats and atmosphere. They have live music on Friday and Saturday nights. During the day you can watch birds - I saw one tearing a part a smaller bird on one of the chairs, which was an unusual but interesting experience...
On one last note, the JW Marriott "signature beer" is actually quite nice. It's a kolsch, made by a local brewery and has some nice honey flavors. I would get that again if I came back.
