I have lived in Las Vegas for about two weeks and can honestly say I have visited this Starbucks location 11 times already. Service is pleasant and for the most part, fast.
I will say avoid this location like the plague on Saturday mornings though. I had a free reward and left to pay for my coffee elsewhere because there was a line of 12 cars at the drive-thru that was barely budging. I backed up and decided to try to go inside (even though my pjs didn't match) only to find around 30 people inside. Too overwhelming for me to deal with pre-caffeine!
My second to last visit was probably the most pleasant I have had at any Starbucks, and being a gold member I've been to my share of locations. I pulled my car forward and had my application ready to pay for my coffee when the barista informed me the car in front of me had taken care of it. I am not the type of person to break a nice trend like that so I went ahead and purchased the coffee for the car behind me. Sometimes it is the little things that can truly make your day :).
