Shortly after the surprise announcement that critically acclaimed restaurant Botika is shutting down, yet another fixture at San Antonio’s Pearl development is throwing in the towel. Blue Box Bar will close at the end of August after 12 years of serving up cool vibes and craft cocktails in the north-of-downtown retail and dining complex. “It is with heavy hearts that we announce the closing of Blue Box at the end of next month,” the business said in a Saturday Instagram post.
