Bistro Canaille, the hidden gem of a French restaurant on Fifth Avenue between St. Marks and Prospect, closed back in July "for renovations," which were only supposed to last for a week. They didnt in fact re-open until several months later, and the space looks very much the same as it did previous to its closure. There are a couple glaring differences, though: a much, much smaller menu, and a new name.
Canaille Wine Bar now serves a small (if well-curated) selection of alcohol (two sparkling wines and five of both reds and whites, available by the glass and bottle, two draft beers, and a few varieties of booze), and a small selection of food: bar snacks, cheeses, charcuterie, and a couple specials like a Merguez sandwich and sliders.
Based on the menu, it appears as if they are using their kitchen very sparingly (if at all); offerings are similar to other wine bars in the area, including Wolf and Deer next door. The food at Canaille was always excellent, so it's a shame to see that they've moved away from that. The full menu is below.
