As Velvet Sea noted this weekend (and Gowanus Lounge followed up on this morning), a café called Brooklyn Bean is coming to the corner of 4th Avenue and Carroll Street—a sign, according to the blogger, that the avenue has finally arrived. While we’re not sure if the coffee shop—which is being started by the folks who own Cuppa Cuppa in the East Village and has nothing to do with Atlantic Avenue’s Brooklyn Bean & Tea Company—is definitive proof of that, we’re happy to see a cool-seeming business come to this stretch of 4th Avenue. (High-quality new establishments like Mule and Pacific Standard have congregated on the avenue’s northern end, while the blocks farther south have for the most part been all about condo construction.) The owners say they’re going to open sometime in January and that they’re planning to book live shows. Sounds good to us. GMAP
