Nagele und Strubell stocks higher-end beauty products - think Shishedo, Sisley, Crème de Mer and…read morethe like for skincare and Annick Goutal (plus tons of boutique brands) for perfume. There's even a little makeup - Bobbi Brown and YSL.
I had bookmarked them as a stop because their website advertised them as the exclusive provider of Santa Maria Novella products in Vienna. They do sell the products, but they're not on display - you have to know what you want and then they'll go retrieve it for you from stock. That makes it a little difficult if you don't know exactly what product you need, though the staff is extremely knowledgeable and will guide you.
I was so sad that they were out of stock on the hand cream I came for, though they did offer me alternatives from other brands. You can't beat the service here - they really do know their stuff.
