The three best things to do in New York today

See Interpol rock out in Prospect Park
Interpol's indie-rock limelight moment came in the ’00s, but the band still knows how to churn out solid Joy Division–esque anthems, as heard in their last LP El Pintor. Check them out tonight in the open air of Brooklyn.
Prospect Park Bandshell, Brooklyn,7pm, gates 6pm, $35

Feast on $1 mac 'n' cheese at S'MAC
S'MAC's East Village and Murray Hill locations celebrate their 9th birthdays by selling $1 All-American Nosh, a blend of American and cheddar cheeses, mac all day long. More money for ice cream later! (Limit one per person, not valid for delivery.)

Find love (or at least a new book) at The Strand's Boozy Book Swap
The Strand is hooking up with OkCupid to help word lovers, well, hook up. The evening will have plenty of talk about authors and their works, prizes and some boozy drinks to clink with your new literary-minded friends. Register through OkCupid.
