Cops booted an unruly group of city teachers union officials from a posh Albany eatery after they caused a ruckus over their dinner tab, the Daily News has learned.

Paul Egan, the union’s political and legislative director, set off the fracas – claiming the quail he was served, and finished, wasn’t large enough – sources said.

Egan and about two dozen other members of the United Federation of Teachers spread over three tables at the swank bistro Marché inside 74 State, a boutique hotel down the block from the state Capitol. . .
