Big Ang was honored at a disco wake in Brooklyn, and by the look of the crowd, it got super emotional.

The wake was held at a Brooklyn funeral home.  "Mob Wives" star Renee Graziano says Ang looked beautiful in the open casket.  Other who attended included Janine Detore, Ang's sister and her estranged husband, Neil Murphy.

A member of the cast tells TMZ, Karen Gravano was persona non grata.  One cast member told us the reason ... "No rats allowed."
