Whether you raise a glass or dip into an endless bowl of salsa, celebrating CINCO DE MAYO has become as American as TMZ and gas-guzzling SUVs. We’re not sure why a Mexican military victory over the French way back in 1862 has become an excuse to party hard, but whatever. We recommend joining the BLOCK PARTY in Virginia Highland, hosted by Pozole Nuevo Latino and Tequila Bar and Limerick Junction, featuring live music, a piñata-smashing contest, a hot-pepper-eating competition and more. The party starts at 4 p.m. behind the pub (enter from Greenwood Avenue west off North Highland). Admission is $5. www.atlantacincodemayo.com.
