This cozy underground treasure punches well above its weight with outstanding live music & sound. My evening with the Malika Tiriolien quartet was unforgettable. Nice food & drink selection including fine cheese & a small but choice list of non-alcohol beers.
This is an incredible bar. The whole place works like a beautiful Swiss clock. I had the privilege of being seated where I could see the whole bar at work. The food was delicious & beautifully presented, the service was seamless (never ran out of water), prompt & efficient. & we could really focus on the great music.
Nice jazz place with live jazz bands. Place has some charm with lights & candles & of course piano. Food was good? But pricey. Cover charge for the show is 15$ & lasted 1 hour only. We expected longer time. Place was noisy even during the show.

What an incredible first experience at Diese Onze Jazz Bar! My coworkers told me this place was a true institution for jazz in the Plateau neighborhood, & I couldn't agree more. We were there for Big Band Tuesdays with Joe Sullivan & it was simply spectacular.
The place was absolutely packed for the Tuesday 7:00 pm show, which speaks volumes about its popularity. Seeing a 17-musician Big Band on such a small, intimate stage was truly impressive. The passion & energy from the musicians were absolutely contagious-it was a breathtaking show! You absolutely have to call & book ahead of time, as this place is incredibly popular.
The entire night was exceptional, not just the music. The food was great; our poke bowl & burger + dessert were all delicious. A huge shoutout to the server who was working all the tables; she was so friendly & provided amazing service despite seeming to be the only one working, along with the fantastic bar staff of course!
This was a great evening out, & it certainly won't be my last. If you're looking for a genuine, high-quality jazz club in Montreal, Dies Onze is the place to be. Can't wait to go back!
The band was amazing, the vibes were great. 4/5 because they were not flexible on the menu at all. No sides or small plates. Server seemed annoyed. The cocktails were really good.
Stumbled into Diese Onze completely by accident & it turned into one of the best nights in Montréal.
Amazing jazz, great performance, good food - & total speakeasy vibes.
Such a hidden gem.
Excellent service de la part de notre serveur Pierre qui à été courtois, rigolo, agréable & approprié. C'est rare ces jours-ci de voir des serveurs avec de la classe & du charme comme lui. Excellent équipe, les cocktails étaient délicieux & bien préparés. Nous avons fait une réservation pour trois & nous avons étés placés très proche de la scène en dessous du speaker mais le volume était très agréable.
La nourriture était délicieuse & bien préparée, & le band Jazz très talentueux. Je recommande!
