Native to Japan’s northernmost main island, Santouka Hokkaido Ramen has dozens of locations around the globe—including Harvard Square, Allston, and Back Bay. While several ramen styles are represented on the menu, the signature shio (salt) broth is known for its silky texture and comparative lightness. If you’d like to make it heartier, you can always order extra pork and a soft-boiled egg to your bowl. All Santouka locations are open for dining in and takeout.
