Gabriel Aubry -- REUNITES with Daughter Nahla

Gabriel Aubry spent some long-awaited quality time with his daughter Nahla today ... for the first time since he and his baby mama Halle Berry called a truce.

As we previously reported, Halle agreed to drop the restraining order that prevented Gabriel from having any contact with his 4-year-old daughter.

Gabriel was still sporting shades during the meeting ... covering up the shiner he received at the hands of Halle's fiance Olivier Martinez during a Thanksgiving Day brawl at Halle's place.
