Tucked away on Rue de Montreuil in the 11th, Once Cocktail Bar is the kind of place you walk past a dozen times before finally pushing the door — and then you're hooked. The bartenders here take their craft seriously without taking themselves too seriously, turning out inventive, atypical cocktails you genuinely won't find anywhere else in Paris. With a 4.9 Google rating from over 430 reviews, this is a neighborhood bar that punches well above its weight.
A tiny rue de Montreuil bar where bartenders craft atypical, off-menu cocktails so good that visitors keep coming back every trip to Paris.
Go early in the evening (around 5-6pm) on weekdays to grab a spot at the bar — it's small and fills up fast, especially on weekends.
The 11th's best-kept cocktail secret
Once Cocktail Bar doesn't try to be the biggest or the flashiest bar in the 11th — and that's exactly why it works. You'll find it on Rue de Montreuil, a street that's quietly become one of Paris's best corridors for food and drink. Inside, it's low-lit and intimate, with just enough room to feel like you're in on a secret. The bartenders are the real deal: they'll chat with you about what you like, then build something off-menu that somehow hits every note. The cocktail list itself is atypical — these aren't your standard Spritz-and-Mojito affairs, but genuinely creative recipes you won't find elsewhere in the neighborhood.
What pushes Once into five-star territory is the consistency. Regulars on Tripadvisor and Google mention coming back every time they visit Paris, and it's easy to see why: the welcome is warm without being overbearing, the drinks are meticulously crafted, and the atmosphere stays buzzing without ever getting chaotic. It's open Monday through Saturday from 5pm to 2am, which makes it a perfect late-night anchor after dinner nearby. If you're tired of overcrowded cocktail bars in Le Marais where you can't hear yourself think, this is your spot. Go with one or two friends, sit at the bar, and let the bartender guide you.
