If you are looking for afternoon tea in Vegas, this is it. Bellagio (Petrossian Bar) is great too but you don't get a view like you do here and the food isn't as pretty. However, the value is better at Bellagio. It is also more casual. The atmosphere here is more formal (not that you have to dress up but it feels that way). You get more food and it's about $5 cheaper per person at Bellagio.
Make sure to make a reservation, the space isn't big. They do have online reservations.
