This is a convenient location and I honestly just stopped in to charge my phone and kill time before I had to grab my bag from the hotel and head to the airport.
I stopped at another location on the strip and the coffee was much better and warmer than this location. The workers were friendly and there was plenty of seating and outlets to charge electronics. This location definitely had the other one beat with comfortable seating and a quieter noise level.
If you need a break and some coffee while shopping at the promenade then I'd stop in but, if not there are plenty of great coffee places around.
