Sweet Polly, sitting unassumingly on Sixth Ave. in Prospect Heights, is a cozy slip of a cocktail bar that looks like the study in that upstate Airbnb you still dream about and serves inventive drinks that’ll make you forget the shoebox you actually call home. Rounding out the experience is a thoughtfully curated selection of oysters, cheeses and small plates, perfect for sharing after you’ve inevitably decided to hunker down and try half the drink menu.
