••• I walked up to Black Tap on Broome yesterday afternoon because I was craving a chocolate milkshake and the weather was relatively balmy, but at 3 p.m. there was a line of mostly young people out the door and around the corner.

I didn’t really believe it—I’ve enjoyed quite a few, but I hardly would’ve considered them newsworthy (and we all know I set a low bar)—until I saw this New York Post article. Black Tap’s shakes are now like Crumbs cupcakes, but worse.
