24-hour diner in the heart of downtown St. Pete. Now open! At 2nd & Second, we believe a downtown diner should be for everybody. That means whether you’re up at the crack of dawn or capping a late night out, you’ll still have somewhere to go. Here you’ll find familiar American classics, along with some fresh takes, cooked up with care and served in a cozy and modern atmosphere. We love the early birds just as much as we do the night owls, so we’re open around the clock.
