I stopped here while out in Vegas because I had a birthday reward to use. Note the ones attached to the casinos do not have the ability for you to use your rewards this location does since it is attached to the shops at Caesar's.
Note that, Starbucks apparently has changed it to where you need to use a birthday reward within only a few days or you lose it.
This Starbucks at the time I went wasn't too busy. However, when I stepped up to the line to place my order the barista left to start making other patrons drinks for the next 5 minutes with the other two baristas. I was like, Wtf?
After she finished doing that, she came up to take my order. I ordered my birthday drink and she helped me max out my birthday reward. It is hard to find drinks since I am dairy free. I just recently learned even the pumpkin spice mix has dairy in it.
