Purity predates Park Slope’s post-eighties resurgence, although it moved from its reliably grungy North Slope location to a more upscale, center-Slope corner, complete with exposed-brick walls and plate-glass windows, at the turn of the millennium. With questions and special requests cheerfully accommodated—and an oversize, laminated, spiral-bound menu chockablock with full dinners, salads, wraps, and sandwiches—Purity remains a trustworthy if less-than-stellar neighborhood fixture. Very good omelettes and breakfast fare, including done-to-a-turn eggs and well-seasoned, thick-cubed home fries, are good choices any time, as are the generous burgers (eleven varieties, including turkey and veg), served with thick-cut fries and crisp romaine and tomato sides. Greek dishes like kebabs and gyros stand out; the salad of mild feta and salty anchovies over clean, fresh greens, with a side-order dollop of the thick-as-sour-cream tzatziki sauce, is both virtuous and tasty. For local tots and late-nights teens jonesing for a sugar fix, the egg creams and ice-cream milk shakes are a standby.Weekend Brunch
Weekend brunch, with steak and eggs, chocolate-chip pancakes, eggs Florentine, and thick-sliced challah French toast, is more about eating well than about leisure; booths fill up and tables turn with prompt frequency, making lingerers feel less than welcome.
