I really love Pinkberry but we had a weird experience at this one. We walked for what seemed like forever to get to this location. Those Vegas blocks are LONG! We were stoked that it was open late at night and super looked forward to our usual stellar Pinkberry experience. And everything was fine, the place was clean, the toppings fresh and beautiful as usual, except that the original tart yogurt was not at all tart! It was completely sweet with no tang to it whatsoever. We were so disappointed, especially for the price. My companion didn't even finish his. I'm hoping this was a one-off, like someone mixed the formula wrong that night, but I won't be back to Vegas to check again for a long time, so this is the review they get. Hopefully someone who has been to multiple Pinkberrys can clarify whether their original "tart" is always sweet here.
