Justin Bieber and Hailey Enjoying Engagement with PDA in NYC Restaurant

EXCLUSIVE

Justin Bieber and Hailey Baldwin will soon swap wedding vows -- but for now, they're happy swapping spit -- and doing it out in the open at an NYC restaurant.

JB and Baldwin were at 12 Chairs Cafe in Brooklyn Thursday for a light lunch, but went heavy on the PDA for everyone else in the place. The two have been on an East Coast tour as of late ... heading upstate to visit Hailey's family then swinging down to Georgia for a personal golf lesson

It's been almost a month since the Biebs popped the question in The Bahamas and the young love buzz is clearly still strong.

As for wedding plans -- those are still in the works -- but it's already on track to be one hell of a honeymoon.
