At the time this corner shop was known as King of Latvia Delicatessen (first photo below). As of 2012 it shares the premises with a pharmacy and does business under the Riga name (second photo); though the ownership is unchanged, the selection of baked goods is smaller. On recent visits, however, I've found no condensed-milk cookies.
