There's two Coffee Beans when you're on the Venetian side- one in the food court and one by the parking lot/Sin City Brewery. I'm reviewing the one in the food court.
I can't really say much. I've been here twice. Once I asked for a specific ice tea which is vanilla and apricot tea mixed together and while it's hot, please put 2 packets of brown sugar. It wasn't a blend, just vanilla, and no sweetener and was still warm without enough ice. Second time I got the "tea of the day" so it was a get out of the fridge and pour situation. The second visit the person was much friendlier than the first who didn't really care.
A-OK rating for one good service day and one bad day. I can't vouch for their consistency.
