I gave this Sephora a not great review a while back, and after visiting over the weekend, I felt like an update was in order.
The staff greeted me as soon as I walked it and didn't ignore me while I shopped. There were plenty of employees even though the store was busier than I've seen it in a long time.
I had a makeover by Alanna, and she was knowledgable and skilled. Had lots of compliments from my girlfriends that night!
The Sephora at Venetian still wins out based on sheer size, but if you're on the south end of the Strip, no need to schlep it up to Venetian for a good Sephora fix.
