Help your favorite barkeeps stay in prime shaking shape at this charity cocktail event, co-hosted by the United States Bartenders’ Guild, on Mon 21. Top-shelf hooch like Plymouth and Beefeater gins and Herradura tequila will feature in drinks devised by a squad of all-star booze slingers: Lynnette Marrero and Jim Kearns (Peels), Jason Littrell (Death and Company), Marshall Altier (1534) and others will be trading turns behind the stick. Cost of entry buys unlimited drinks, snacks from the Freemans kitchen (corn dogs; lamb sliders) and Stinky Bklyn cheese, plus a performance from folk-rock trio the Crooners. Tickets are just $40 and all proceeds benefit career bartenders in need of health insurance. Freemans, Freeman Alley off Rivington St, between Bowery and Chrystie St; second floor. Purchase tickets at 7–10pm; $40.
