The restaurant that started it all—and by all, we mean the Pappas empire—opened its doors in 1967 and has rarely closed them since. Open 24-7, Christmas Eve and Christmas Day excepted, Dot serves comfort food made from scratch on-site, with all the daily blue plate specials and soups du jour you’d expect in an old-school diner setup. If you’re looking for a late-night breakfast, the Houston omelet comes with all the meat you can handle.
