For those who have yet to cram a Mike Isabella-made sandwich down their gullet, the "Top Chef" alum is extending the pop-up version of his forthcoming 14th Street sandwich shop G. The pop-up, which was supposed to end its run at his Italian eatery Graffiato on Friday, will continue through this Friday, offering up G's sandwiches each day during lunchtime. This week, the sandwich selections are being switched up with the cubano panino, the meatball sub and the cauliflower sandwich all available. After the pop-up concludes, Graffiato will serve a rotating selection of G sandwiches weekdays during lunch for dine-in or carry out.
