  • MusicLive jazz, gypsy jazz and flamenco, two shows daily

Dièse Onze is a candlelit basement jazz bar and restaurant at 4115 Rue Saint-Denis in the Plateau-Mont-Royal neighbourhood of Montreal, Quebec, Canada. It has been open since 2007 and presents two live shows daily, with styles ranging from gypsy jazz to flamenco, so the programming is broader than a conventional jazz club. The crowd is a mix of Plateau locals, music lovers, couples and visitors, mostly adults, and dress is casual.

Dièse Onze is a candlelit basement jazz bar and restaurant at 4115 Rue Saint-Denis in the Plateau-Mont-Royal neighbourhood of Montreal, Quebec, Canada. It has been open since 2007 and presents two live shows daily, with styles ranging from gypsy jazz to flamenco, so the programming is broader than a conventional jazz club. The crowd is a mix of Plateau locals, music lovers, couples and visitors, mostly adults, and dress is casual. The atmosphere is intimate and warm, with candles on the tables and a basement room that keeps the stage close to the audience, making it well suited to listening rather than loud socialising. The first show is listed around 6:00 PM, which allows an early evening visit, and a second show follows later in the night. The drinks and food side is built around a tapas-style menu, so guests can share small plates while they listen. Prices are mid-range, around two dollar signs. A music charge applies, but it varies by show, so the exact amount depends on the performer on the night and should be checked before attending. Reservations are advised, particularly on weekends, because the room is small and popular shows fill. The website, dieseonze.com, carries the current schedule and booking information. No phone number is listed here. The Rue Saint-Denis address is within walking distance of Mont-Royal Avenue, Parc La Fontaine and many Plateau restaurants, and the Mont-Royal metro station is nearby, which makes the club easy to combine with dinner or a stroll in the neighbourhood. Weeknight shows are typically more relaxed, while Friday and Saturday evenings draw the largest audiences and are the best nights to book ahead.
