Reservations Not Taken
It may be Union Square-adjacent, but locals know that Katana-Ya is one of the finest spots in San Francisco for a hearty bowl of steamy, soul-curing ramen. Ignore the vast majority of the menu (you're not here for sushi, after all), and skip straight to the good stuff—the karaage ramen topped with crispy-skinned fried chicken is a fine choice, but it's hard to beat the namesame Katana-Ya ramen. It's loaded with pork, gyoza, egg and corn, which may be excessive but is undoubtedly delicious.
