It could be jarring to step off an Arlington street and into a Bolivian home, but Sibarita Restaurant makes an easy transition with warm decor and authentic Bolivian cuisine. Bright yellow and orange walls are hung with intricate metal artwork, and a rear entrance opens up onto a patio lined with potted tropical plants and thatched grass-roof tables that a family of jaguars could call home. The kitchen staff specializes in a range of traditional Bolivian dishes represented by an expansive menu. Guests can savor marinated churrasco steak, tender grilled lamb, vegetable stew with steak cooked in beer broth, or the silpancho, which was recently raved about in the Washingtonian and The Washington Post. Other dishes include Bolivian-style fried chicken with plantains and a variety of sandwiches topped with jalapeños and fried eggs.
