Three men were slashed as they waited for food on a Queens street late Monday, cops said.

The victims — all of whom are accused gang members — were standing on Broadway near Pettit Avenue around 10 p.m. in Elmhurst and had just placed a food order at a deli when another man approached and started slashing the trio, according to police.

The oldest victim, 29, was cut on the head, a 28-year-old on the torso and left arm and a 26-year-old on the left leg and wrist, authorities said.

It was unclear whether they knew their attacker, who fled on foot south on Broadway.

All three men walked into NYC Health + Hospitals/Elmhurst with non-life-threatening injuries, police said.
