Husband-and-wife restaurateurs Anthony Myint and Karen Leibowitz opened the Perennial in San Francisco in January.

With interiors by Paul Discoe Design, sustainable features include a dining room ceiling made from wood shavings and tiles, bar stools, and rugs made from recycled materials. The eatery seats about 70 in the dining room; it holds 100 for a receptions, with room for 110 standing at the L-shaped bar, as well.

Located in San Francisco’s Mid-Market neighborhood, the bar has a speakeasy feel thanks to its backdoor entrance on a quiet side street.
