A perv touched a woman’s butt in a Korean food court in Midtown while she was waiting to get her food — then smiled at her when she confronted him, police said.

The 23-year-old victim was inside Food Gallery 32 on West 32nd Street near Fifth Avenue around 10 p.m. June 23, cops said late Wednesday.

Police provided video of the suspect, who was last seen inside the 34th Street/Herald Square subway station, wearing a denim jacket with a gray hood and a red shirt underneath.

This creep isn’t the first man to smile after committing a lewd act. Travis Jones, 26, was busted Monday for lifting a woman’s skirt after being recognized from his smiling photo on The Post’s website, officials said.
