Anti–Valentine's Day Dinner Class
The Labs at the Brooklyn Kitchen; 100 Frost St., nr. Leonard St., Williamsburg, Brooklyn (718-349-5033)
Forking Fantastic! co-authors Tamara Reynolds and Zora O'Neill are serving up hearts on a plate. Join the pair for their two-hour Anti–Valentine's Day dinner class ($50). The low-pressure tutorial starts with dessert (screw tradition) and progresses through several courses, including roasted radishes, bitter green salad, duck heart on toast, and duck-leg confit. Whatever your Valentine's Day sentiments, it's a welcome respite from takeout.

Anti–Valentine's Day Party
The Diamond; 43 Franklin St., nr. Calyer St., Greenpoint, Brooklyn (718-383-5030)
Singles get $1 off drinks during this beer-centric bar's Anti–Valentine's Day Party. (Lucky for the beer-slinging staff, revelers "must effectively prove singleness to the bartender," says Dave, the owner.) A four-on-four ladies-versus-gents shuffleboard tournament kicks off at 7 p.m., vying for the prize of a $25 bar tab and a crown of Reissdorf Kölsch. Pair your beer with black-frosted cupcakes at the bar for $2 apiece. D.J.'s are instructed to keep the playlist sap-free.
