The first U.S. outpost of this Japanese ramen brand—which opened to a line of customers hundreds deep—promises to serve up its bowls of broth within 15 seconds, Eater says. Prompting extreme focus on the food, customers are encouraged to dine solo in booths made for one, where they place orders by writing them on slips of paper wordlessly handed to servers. For those who wish to interact with others, a section with more traditional table seating is available.
