More than a few guys in Ghostbusters costumes lined up to meet Dan Aykroyd, owner of Patrón tequila and Crystal Head Vodka, and, oh yeah, famous Canadian actor and comedian. How does he drink his tequila? “Patrón Plata straight, or the XO with milk — a Mexican Russian!” On Friday, Aykroyd will be at the Northgate Mall Liquor Store in Burnaby, from 2-4 p.m.
