Overall, Diese Onze Jazz Bar is seen as a true Montreal jazz institution with a distinctive vibe that blends great music, a cozy setting, and dependable hospitality, making it a go-to for jazz lovers and a memorable night out.
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.

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!
A classic jazz club with outstanding music. Also friendly helpful waitstaff & reasonable food at reasonable prices. Basement location provides an atmosphere that's a nice mix of bar vibe, intimacy, & wood-panel elegance.
$15 cover.
We suggest you reserve for dinner so that you get a good seat with a view of the performance. Otherwise you'll likely still get seated but no great view.
This is truly a Montreal institution for jazz lovers. Wide variety of music showcased each week, from big band jazz to intimate duos & trios, all top notch. Sound is excellent from almost anywhere - it's a very small club (& reservations are definitely recommended) with a small stage which makes for interesting layouts for the larger groups. Cover charge is reasonable (varies but averages $20) with a reduced price if you stay for the second set. Note if you do make a reservation you are expected to order at least some food.
It's easy to miss the basement entrance walking by though there's a small signboard. Note that due to the structural reality of a basement, there is a column that can partially obstruct certain seat views, especially from the curved middle off the bar. (That's the only reason I didn't give it 5 stars for atmosphere, otherwise it's a fantastic place)
My experience is that the staff are professional, friendly & provide good service (some others have apparently felt otherwise). It's a small place with few staff so the busy servers & bartender have a lot to juggle & do it well.
The bar menu (including mocktails) is pretty extensive, my recent house specialty cocktail order was excellent & generously sized, yet still only $15, pretty standard.
I've read that the food menu was upgraded recently. I can say that my'tapas' (small plate) chowder bowl - yes it was big bowl - was fantastic & very reasonably priced ($20) - rich flavorful broth, generous portions of fish, mussels, clams, shrimp, calamari, & octopus - all very fresh, hot & served with four toasted baguette slices. I also had an amazing chocolate mousse cake with an attractively plated side pool of berry sauce & berries - a large portion again reasonably priced at $15. My friends had a couple of the plats (main dishes) that looked great. (Menu is available at their website.) They come often & love the food so that is another vote of confidence!
The total bill (drink, food, cover charge, Quebec tax & tip) came in at around $90 & it was money well spent for a superb evening of live music & food. Friendly customers too. It's an institution for good reason!
Note that while the staff are all bilingual, usually the performers (if local) only will talk in French from the stage.

Diese Onze is a great jazz bar with amazing live performances & a cozy vibe! We had the burger & scallops-both pretty good. Definitely recommend calling ahead to make a reservation for the best seats (plus you get a small discount!). A must-visit for jazz lovers!
Amazing & cozy spot with great music & even greater service! The bartender, Lucas - was super attentive & fun, & even offered a glass of champagne on the house
Super bar jazz avec de très bon musiciens! J'y vais souvent les lundis jazz latin & c'est vraiment super le personnel est très aimable & c'est un belle ambiance de gens respectueux! Amenez-y votre S/O elle ou il va adorer!
Je ne peux pas commenter sur la nourriture je n'y ai jamais goûter mais elle a l'air bonne de ce que j'en aperçois! On peut voir par une ouverture les deux cooks cuisiner & ça a l'air très propre & bien fait!

We saw the Big Band avec le Benjamin Deschamps, & it was not be missed. This 17 piece jazz band was so tight & amazing. I sat at the bar with my family, & the staff was friendly, attentive, & we had a great view of the staff in the kitchen clearly enjoying the show as well as they bopped along. 100% would return to this venue, & would follow the band anywhere they go.
Came across this Jazz Bar while visiting Montreal for the weekend. The Host was lovely & super accommodating, he found me a seat even though they were having a Christmas Special & the place was packed with reservations! The music was great & the basement was sweet & cozy.
Amazing little spot. Downstairs joint with a bar & great food. The burger was delicious. Cheesecake was so good i would go just for dessert & the show. Fantastic staff who were extremely nice & very helpful. Great quintet was playing. Loved it here. Really good chill spot to wind down after a long week.
Cozy jazz bar with great atmosphere, a variety of engaging performers, good service, & delicious food. I go here regularly & usually get the cote de boeuf & absolutely savor it! The Latin night earlier in the week is really lively & they get traditional jazz performers on Friday & Saturday. On the weekend, it's best to make a reservation seeing as the place tends to fill up. You do this by leaving a message on an answering machine. They've always called me back to confirm & my place is always reserved when I get there, so the system obviously works. I'm glad to see this place thriving!

Live jazz resto-bar. Always great musicians playing here, different themes depending on the day of the week. Located in the basement but very cozy. Excellent service & great atmosphere. A must visit for any jazz enthusiasts.
Great jazz bar. However be careful about reservations. If you don't reserve in advance you might find a table from which the stage is not seen. Cocktails are acceptable.
