Add Max Brennan to the long list of East Village business owners who have opened outposts in Williamsburg. Gothamist reports that Mr. Brennan, an owner of Lit Lounge, will open a new “swinging 60s-type jazz club” called The Flat on the other side of the East River later this month. Mr. Brennan, whose fellow Lit-owners celebrated the bar’s 10-year anniversary last week, will join familiar East Village eateries like Max, Crif Dogs, Mama’s and Cafe Mogador that have followed the L train east.
