The Map Room’s mostly monthly Beer School series continues next Saturday at 6 PM, with Mickey Finn’s brewmaster Greg Browne leading a tasting and discussion of Australian and Asian beers. The classes tend to be mobbed, so this time around the bar’s instituted an advance ticket policy. Tickets ($15) go on sale Monday 11/20 at 1 PM. You must go to the Map Room and purchase a ticket in person, in cash. Come Saturday, no ticket = no school for you.
