I found it, Yelp! It's on the 4th floor on the Cosmopolitan where the hotel pool is hidden by the cabanas. Inside, it's pink and black all over! It's pretty in the girliest way. The decor is so modern and classy just like the Cosmopolitan.
They have ice cream bars and sorbet. I opted for the sorbet as it seemed more worth the price than an ice cream bar. I went for the Miss Mossa as suggested by the employee. Though she said it was the lightest of them all and sweet, I could taste the alcohol as I swallow. The Miss Mossa has a candy gummy ginger infused with vodka. BE CAREFUL. It was an blood orange flavor. My boyfriend got the Snow Bunny (via my order for him) and it was also very strong in alcohol. This one is raspberry flavored with pop rocks on top. Both sorbets were made right when we ordered. The ice cream bars on the other hand are pre-made and very icy. We got a sample of the watermelon Patch.
There's tables inside and outside by the edge of the hotel where there's a great view. I also got a lot of water because I was getting buzzed off ice cream. Seriously, how does that happen? I will be back next weekend with Sidney T. This time I think I'll just share one with someone because I could not finish my $18 sorbet.
