I'm giving this place 5 Stars because the girl who helped me out the night I visited was the SWEETEST thing ever! Very helpful, and kind.
I purchased the bling pop in Black ($22, but the ones with charms are $25), personalized mints($3.25, I think?), and a Lollipop Refill Pack ($12 for 3 custom Pops) I haven't had a chance to crack open my packages yet, but I'm sure I'll love anything that comes out of this place.
Definitely give it a shot if you're staying at, or visiting MGM Grand. It's such a fun environment :)
