Amaya Espinal got a hero’s welcome in the Big Apple after her winning run on “Love Island USA” … including shaking it with a few of the New York Knicks’ finest.

The ‘LI USA’ season 7 winner pulled up to Sei Less — a fine-dining Asian Fusion restaurant in Midtown Manhattan — Friday night after months in the villa … and, she and some friends decided to go all out at the celeb hot spot.

Our sources say Sei Less is one of Amaya’s fav restaurants, a place she frequented before achieving fame on ‘Love Island’ … but, yesterday was a change for Espinal, who got a private dining room and was mobbed by fans while walking through the joint.

Always polite, Amaya stopped to take photos and sign autographs for everyone who wanted one … including the restaurant’s cofounder, Ivi Shano.

While in her private area, a few dancers for the New York Knicks stopped by to move and groove with her for a minute … and Espinal showed a little skill on the impromptu dancefloor — so maybe a more formal invitation to Madison Square Garden could be in her future.

The restaurant had a few special surprises for her — including the “Amaya Papaya,” a dish named specifically for her.

We’re told Amaya and her friends arrived at 10 PM and dined on rock shrimp, chicken satay, spicy tuna crispy rice … and they downed a few Lemon Drop Martinis, too.

Our sources say Amaya’s got an event at Sei Less scheduled for next month around the time of the “Love Island USA” reunion … so, stay tuned for more info on that.
