Better get your bottomless brunch on before this Manhattan attorney gets his way.

Lawyer and longtime East Village resident Robert Halpern has filed a suit against the State Liquor Authority over a loophole to a  law that prohibits the sale of unlimited alcoholic drinks over a set period of time for a fixed price. 

Weekend brunch packages with unlimited mimosas or Bloody Marys are legal, according to the law, because the service of alcohol is “incident to the event,” i.e., your plate of eggs and bacon.

Halpern — whose neighborhood has seen exponential growth in active liquor licenses over the past few years, he writes in court papers filed Wednesday in Manhattan Supreme Court — argues that “bottomless brunches lead to more drinking in the [East Village], which leads to more noise, more crowds, and more uncivil behavior.”

If the litigious prohibitionist sounds like a grinch, take note: His suit names 15 bottomless brunch deals that could bear the brunt of the court’s scrutiny.
