Had such a great time this past Thursday night (10/22/15). Fair amount of open seating in the lounge area; perfect for people watching and eyeing the goodies at the Swarovski crystal kiosk (only in Vegas and only at the Palazzo). Not the largest selection of champagne, but it was a damn good one. Ordered a bottle of Veuve for $120 and a glass of Laurent-Perrier Cuvée Rosé for $28. Good times.
Very friendly service, little bit of bar snacks to munch on (we didn't partake, but I'm sure they're scrumptious).
Would definitely come back the next time in Vegas and enjoy more bubbles from this little piece of champagne heaven.
