Owner-chef Takeshi Sato had never given the humble hamburger a second thought before he began his apprenticeship at Tokyo’s famed Firehouse. But he’s certainly a fast learner: just a few years later, he’s creating gourmet masterpieces at Akasaka’s Authentic. From simple cheeseburgers to the monstrous Authentic burger—a mad combination of three beef patties layered with chili, egg, cheese and bacon—Sato personally crafts each sandwich into that perfect balance of crispy toasted bun and juicy, 100 percent beefy goodness. Not to be missed are the bacon cheeseburger, with three thick strips of bacon that are double-fried to an exquisite crunchiness, and the original broccoli cheeseburger, featuring a patty piled high with sautéed broccoli florets and drizzled with Monterey Jack cheese. Five fresh and healthful deli-style sandwiches are available for those looking for something a little different. While the queue is often out the door during lunch on weekdays, Authentic really shines at night—with a perky ska soundtrack and playful university-like atmosphere, it’s a funky and relaxing spot to grab a burger and a beer on the way home.
