Let’s face it: normal Mother’s Day events are a little blah. Instead of taking your mama to one more brunch, why not bring her to Trina’s Starlite Lounge, which is holding a highballs party at 7 p.m. on May 9? The event, co-sponsored by drinkboston, will offer classic cocktails like the Presbyterian (bourbon, club soda, and ginger ale) and the Moscow Mule alongside a selection of hors d’oeuvres like pigs in a blanket. It all sounds very Mad Men and it should be a fun way to break the Mother’s Day monotony. Tickets, which cost $35 in advance or $40 at the door, may be reserved by calling Trina’s.
