Taylor Swift and Travis Kelce shared an intimate dinner at an NYC restaurant Friday night -- and the two were a picture of happiness ahead of their much-anticipated wedding!

TMZ obtained a photo of Taylor and Travis sitting in a corner booth inside Sartiano -- an Italian restaurant in the fancy Mercer Hotel in Manhattan's SoHo neighborhood.

We're told the power couple was having a blast -- smiling, laughing and talking the night away. Our source did not see any PDA ... but said Taylor and Travis looked sweet and are definitely in love!

Earlier in the night, the two seemed like a married couple -- although they're not just yet -- as they walked hand-in-hand through Soho, heading toward Sartiano's for their dinner.

Paparazzi were out in force, shooting video of the lovebirds and zeroing in on Taylor's perfectly toned legs sprouting from underneath her black mini dress. The shutterbugs got the pair going inside the restaurant and coming out after their meal.

BTW, the commotion for the couple at the restaurant was so big, someone in the crowd asked if they were all waiting to see President Trump!

As for their wedding ... no official word yet on when or where Taylor and Travis are tying the knot. They've been keeping their wedding plans ultra-secret.  

All will be revealed, though, in due time.
