There's just something very right-on about the food at Prune, a cozy treasure of a restaurant serving eclectic, well-executed American food from cult chef Gabrielle Hamilton. The choices change with the season, but you might find braised rabbit legs in vinegar sauce, whole grilled fish with fennel oil and chunky sea salt, or roasted marrow bones with parsley salad and toast points. If they're on the menu, try the pillowy, fired sweetbreads. There's usually a wait, and the quarters are very cramped, so don't expect to feel comfortable lingering at your rickety wooden table. Desserts, like ricotta ice cream with salted-caramel croutons, are irresistible, and on weekends lines form early for the restaurant's deservedly popular brunch.
