About
Saiwaii Ramen opened around 2010 and has become a cornerstone of the Outer Sunset's dining scene — a small, cozy restaurant where Japanese family ownership and a focused menu produce consistently excellent ramen. The broth-based menu covers tonkotsu, miso, spicy garlic, shoyu, shio, and chicken ramen, with a rotating selection of appetizers including potato croquettes, gyoza, agedashi tofu, and karaage. The cooking is straightforward and traditional: rich broths built over hours, house-made toppings, and noodles of the right thickness for each style. Regulars praise the warmth of the staff, the portions, and the value — qualities that have kept the restaurant full for over 15 years through every wave of SF's restaurant scene.
