“I feel like a jack-in-the-box that’s somebody’s been cranking and cranking, and finally the top just broke,” Michael Voltaggio explained with palpable energy yesterday about the frustration he’s felt in not being able to open his restaurant ink. sooner. But the usual delays did not slow down the chef’s ambition or mind, as he sprang a big surprise on the assembled media: he is opening another restaurant next to ink. called ink.sack, a neighborhood sandwich shop with low prices and very original takes on lunchtime classics (including a sandwich named for Jose Andres). Not only that, he’s opening it tomorrow! The Top Chef winner and opening chef de cuisine of The Bazaar gave a tour of both ink.sack and ink. Come take a look at both of the spaces, the sandwiches, and the homemade ice cream that are bound to make this one of the busiest blocks on Melrose in the coming weeks in this slideshow peek at ink. and ink.sack.
