Love this Starbucks at the Westin. It's open 24 hours a day. It was even open on NYE!
Also I ordered a Salted Caramel Mocha Frappuccino this morning and they actually had the salt. All other Starbucks (LA, NY) I have been to the last few months were out of the salt.
The cashier and baristas were friendly enough even though they working NYE.
