Whenever I go to Las Vegas, I make it a point to go to the Sephora located at the Venetian. This store is deadly to my wallet, but so much fun at the same time. It is a big store that is jam packed with all kinds of cosmetics and perfumes. I love how you can try and get samples of everything in the store. With cosmetics, this is very important because there won't be any surprises in the color, texture, etc. of it.
My husband always sits in one of the chairs up by the entrance and lets me do my thing! I'll be in Vegas in May and this will be my first shopping destination!
