Petrossian Bar

To me this spot was all about atmosphere - the piano and the great location made for an awesome date night! Wine selection was also very good.

We made reservations at Petrossian's for my son's birthday and were excited to go. Unfortunately his plane was late, and we had to cancel our reservation. When we got my credit card statement, we saw a charge for the missed reservation. I called the restaurant and talked to Diana - wow was she fantastic!! Diana looked up the reservation, and talked to a manager. She told us that she was refunding the reservation fee. I am very impressed with this service, especially Diana's ability to deal with a frustrated guest.
I am now looking forward to my next visit to Vegas (coming in a few weeks) and we will definitely be going to Petrossian's!

Great food and cocktails

Wonderful bites and drinks!

Being loyal to Mgm
Just had the most incredible experience everything from start to finish was absolutely top-tier. The service was flawless friendly, attentive, and genuinely welcoming without ever feeling overbearing. You could tell the staff really cared about creating a great atmosphere.

The drinks? Perfect. Thoughtfully crafted, balanced, and served with just the right flair. Whether you’re a cocktail lover or just enjoying a classic, you’re in good hands here.

But what truly set the night apart was the live piano performance. The woman playing was beyond amazing not just talented, but soulful and deeply connected to every note she played. It wasn’t just background music it was a performance that made the whole evening feel magical.

The atmosphere itself was nothing short of astonishing. Cozy yet elegant, vibrant but relaxed the kind of place where time slows down and you find yourself truly present, just soaking it all in.

Can’t recommend this place enough. Whether you’re out for a romantic evening, catching up with friends, or just treating yourself to something special this spot delivers on every level

There’s a quiet confidence to Petrossian—like it knows it’s better than most lobby bars, but doesn’t need to brag about it.

The caviar bites? A study in restrained luxury. Salty, smooth, rich—like they were designed for people who collect watches instead of followers. And the martinis? Flawless. Not fussy. Just crisp, cold, and consistently right.

Service hits that rare sweet spot between formal and friendly. They see you, they get you, and they let the experience speak for itself.

It’s not flashy. It’s not trendy. It’s timeless. One star off only because the vibe can feel too subdued depending on the hour. But if you know, you know—Petrossian’s a gem for those who don’t need a spotlight to shine.

Stopped in for drinks in April 2025. Great little late night option with lite snacks and small plates. Great to decompress. Seating can be a challenge for large groups. Five or less works well. The decor is nice, service equally good (at least the night I was there). Drink and whiskey choices are plentiful and you can ask the waitstaff to surprise you and they'll concoct a elixir of good choice. Drinks are pricey. Food/snacks too. Don't be drunk buying here. You'd run up quite a tab otherwise.

Afternoon Tea

We came here on a Saturday around 3pm for afternoon tea. Price is $55 per person for regular afternoon tea which includes Scone, sandwiches and desserts. You get a choice of tea so we had the camomile and vanilla tea.

The tea was good, the sandwiches were okay and dessert was average. No wow factor to the food. The ambience was nice since you are able to watch people however you are seated in the back and can’t listen to piano.

For the experience of an afternoon tea should be okay however you won’t be returning for a second time.

The lights caught the sugar rim like a promise… glinting green on marble as the city pulsed just outside. In the hush of the Bellagio lobby bar, Orlando moved like a man who knew things: proportions, secrets, how to turn a whisper of gin into something that sings.

Lavender and jasmine curled in the air like smoke from a femme fatale’s cigarette, and the cocktail he handed me wasn’t just a drink. it was a story in a martini glass.

Frothy, elegant, and dangerously smooth. Noir Vegas, par excellence.

Wonderful staff. Thank you everyone. Thank you Moses. Thank you David Osbourne. Love the upscale lounge. See you next time! Was a pleasure.
