Café society blossoms along Newbury Street, particularly at Sonsie, where a well-heeled crowd sips coffee up front or angles for places at the bar. Lunch and dinner dishes, such as charcoal duck breast and leg with brown rice and five-spice turnips, are basic bistro fare with an American twist. The restaurant is a terrific place for weekend brunch, when the light pours through the long windows, and is at its most vibrant in warm weather, when the open doors make for colorful people-watching. A downstairs wine room meanwhile offers more intimacy. The late-night menu (nightly until 12:30 am) is perfect for after-hours cravings.
