Sabu's Coffee (5708 Oakland Avenue; 314-781-9500) has closed. The café opened in June 2010. According to the tipster who passed along the news, its final day was in the middle of last month.
Hadn't heard of Sabu's till now? Its location might be the reason: a retail storefronts in one of the office buildings that face Interstate 64, just west of Forest Park Community College.
