Came here on a Thursday morning. There was no line and the store wasn't too busy.
I paid $14 for an acai smoothie. The acai was melted. It was hard to eat it off a cup..but who am I to tell them how to serve acai + fruits + nuts and stuff anyway. That's up to their executives.
I really don't mind paying $14 in a Vegas Strip joint, especially in Cosmopolitan..but I expect better quality from a place like this.
Service was friendly.
