We got the injured NBA star leaving Mastro's in Bev Hills Friday night -- he's in town for All-Star Weekend festivities -- and asked if there's any ongoing beef between him and the Wizards center ... he shoots it down right away.

Here's the backstory -- Gortat tweeted about a great "team" victory after Washington won its first few games without Wall, which many considered a shot at the star. Wall responded by saying he gives Gortat "the most spoon-fed baskets ever."

The 2 reportedly had a meeting to hash out their issues last week ... and it seems like it worked.
