Brooklyn Heights is a place of quiet but enormous wealth, where actors and old-money types hide mansions and two-car garages behind tasteful, unassuming brownstone façades. So it’s fitting that the best restaurant in the neighborhood is a tiny little place wedged onto a mostly residential street. Iris Café has grown from its coffee-and-pastries roots into something truly special: The cooking has remained homey and unpretentious, but with an energetic, creative edge, and complicated octopus dishes and kale croquettes nestle next to short ribs and roasted chicken. But the best meal of the day at Iris is always breakfast. Try the chilaquiles or the shakshuka, the spicy Israeli tomato-egg dish, with strong coffee and fresh cold-pressed juices. Your tab for two still won’t be much more than $30.
