EXCLUSIVE
If there's one thing Harry Styles didn't get enough of while dating Taylor Swift ... it's clam -- because that's pretty much the first thing he ate following their breakup ... and TMZ has the pic.
The "One Direction" singer -- who just ended his record 2-month relationship with T. Swizzle -- was in Brooklyn Sunday night, when he got a hankering for some Italian ... and swung by the famous Don Peppe's with a pal.
We're told Harry appeared extremely chill throughout his meal -- happily noshing on veal parmigiana, shrimp luciano over linguini, and his main course ... a steaming pile of clams.
And how about this ... we're told it was Harry's first time trying clams in his entire life. Huh ...
