Would give this 2 1/2 stars if I could.
Overall this place just didn't deliver. The setup is cute, but a little too bright. It also gets very noisy, probably because there is very little space between the tables.
The menu showcased many odd / surprising food combinations. I came in curious to see how these would turn out. The trout tartar was nice but could have used more salt and a little extra punch. I then had the tuna and sweet breads, which were just sitting on chopped zucchini and a soggy, watery tomato sauce - which also could have use more salt. The tuna wasn't cooked well either. They offer nice proteins but the execution was too poor for us to enjoy. However, those who stuck with something more classic (red meat options) were hugely satisfied and loved their dishes. Maybe the secret is not to get too adventurous when eating at La Prunelle. Other good side is the BYOB because the prices are quite high - around 50$-55$ per person, without tax / service. Too many good places in Montreal for me to go back there.
