The riverfront of the Hostess City of the South is undergoing some radical changes, transforming underutilized space into new districts, bringing more of the city’s hidden treasures into view. On the site of a former power station, the newly opened Plant Riverside District offers multiple restaurants, most with river views and outdoor seating, such as the German-style Riverside Biergarten. Its towering dual smokestacks hover above music venues, morning mindful-yoga classes and the new JW Marriott Savannah, which features a rooftop lounge. About a mile east is Eastern Wharf, a 54-acre development that will include the Thompson Savannah. More buzzy openings include The Jules, housed in a renovated 19th century mansion on the Historic District’s Chippewa Square, and the 3 Points Food Court, a food-truck park that hosts yard games, movie nights and live musical acts. —Janine Clements
