We came here each night for our nightcap and took in the crowd. Great folks there to meet your libations

What a fantastic place for a cocktail.Our server was so good, so friendly and attentive.I had one of the best Espresso martinis I’ve ever had…. Well to be honest, I had THREE of them they were so good!

We were in the Bellagio looking around and wanted to sit down and have a snack and cool drink. This piano bar off the lobby looked very nice so we gave it a try. VERY nice, great staff, great piano player. I had a shrimp cocktails (nice big shrimp!) and my spouse had a charcuterie board. Fruit and cheese, even a piece of honeycomb. The food and atmosphere were really good. Recommend it!

Great place for a night cap, people watching, or just to chill out. Great selection of drinks, live piano music and when you feel the need to splurge on your Vegas trip... caviar service. Been here many times, and now is a must stop whenever I go to Vegas. A word of advice: even though they are open until 2 AM, be aware that their kitchen closes at midnight.

This is a classy lobby bar that has great piano playing, terrific ambiance and delicious snacks and beverages. Its a nice spot to people watch and relax. Service was friendly and quietly refined. The presentation of the caviar items and the martini in a block of ice was incredible.

Gorgeous piano bar, Manhattans we’re amazing. Hard to beat location right within Bellagio lobby.

This is an incredible place with original drinks/bites! It’s different for taste, but very original! The piano amazingly accompanied our time, the location is perfect for tourists, or visitors!Thank you!

I’d always noticed this bar although never thought much about going there given live piano music isn’t really my thing. We noticed though a strip of tables that run along the casino floor that were a bit more peaceful. We stopped in here for drinks and nibbles before heading to a show later that night. They don’t take bookings FYI. We polished off some bubbles and Chardonnay along with a delicious and generous cheese board and a vegetable crudité plate. Despite the frantic pace of the Bellagio, this was a welcome reprieve from that. Service was also friendly and warm.

As there was a party of 14 of us, we prebooked Petrossian as it looked like it was going to be quiet and refined, a lovely place to finish off the evening after our meal at Picasso restaurant within the hotel. Unfortunately I had not realised it was on the same floor as the casino, right after the lobby main entrance in full view of the casino. The result was that our ears were assaulted by the chime of the slot machines instead of the tinkle of a piano playing! To add insult to hearing injury, the cocktail waitress sneered at me after I asked for more ice to be added to my negroni cocktail. I appreciate that it may not be the classic way to serve a negroni, but as I am the customer and it is my choice, she should have shut up and just bought the extra ice to me. All in all, I would not recommend and would not return to a bar that is not quiet and does not give good customer service.

To explain…. Godiva chocolate liqueur isn’t available in Canada. In order to develop our palates, we decided to drink these everywhere we went. The hands down winner is this gorgeous piano bar at the Bellagio. Furthermore they offer the most decadent of bar nibbles which takes them to a whole new level.
