The Cup is the coffee pit stop option for those who are sick of looking at all the things they can't afford at CityCenter's Crystals mall. Crystals has a few high-end restaurants but no traditional food court. The Cup is really the only place you can grab a quick snack.
The black, white and orange color scheme with modern, angular interior design makes it feel like an Apple store mated with a Starbucks. Once you get beyond that, you realize it's just another coffee shop. It's very clean and when I was there, not too busy. The counter guy named Brock made my chai latte and asked for feedback on the quality of his work. Could have used a tad more chai but it was still pretty good.
They also have an assortment of designer chocolate treats and your typical croissant/muffin fare. I got a double chocolate oreo, which is really just an oreo cookie encased in milk chocolate. At $3.50 it's clearly a waste of money but maybe some of the other items are a little more fulfilling.
