We're staying at the SLS and the Perq seemed like a super convenient, cute coffee shop. I ordered an acai bowl and an earl grey latte. Both were so incredibly sweet I couldn't even finish them. They weren't cheap either so it was a bit disappointing. The service, as mentioned in other posts, needed some help too.
I wouldn't come here unless staying at the SLS, and if I wasn't so intrigued by the boozy affogato, I wouldn't be back during my stay.
