We usually stay at the Paris so this is my go to stop for a chai tea latte. The chai tea latte is just ok though and the love is usually ridiculously long. I totally have to wait 10-20 minutes in line and then have to wait 5-10 more minutes to get what I ordered.
I stop by here because it's convenient, but it's nothing special. I'd recommend getting there early in the morning so that you don't have to wait in a really long line. Even at 9 (early Vegas time), the line has already gotten pretty long.
I may not be impressed, but if I want caffeine, I'm sure I'll be back again next year since it's convenient.
