Tabelog ratingSanwa offers a highly focused take on Italian-Japanese cuisine from its small basement space in Shirokanedai. The experience is built around two pillars: masterful charcoal grilling and an array of exceptional handmade pastas. The kitchen's signature is its prosciutto with hot, puffy niocco fritto, a dish praised in nearly every review for its perfect execution.
Guests consistently rave about the pastas, from dense pici and house tagliatelle to the famous mushroom spaghetti and a cold pasta with uni and crab. The charcoal-grilling is another highlight, with the chefs treating each meat—be it Ezo deer, bone-in lamb, guinea fowl, or Obanazawa beef—with a distinct technique that makes each plate feel unique. The focaccia, green pea risotto, and confident wine pairings also draw frequent praise. The set course is generous, but guests appreciate the option to add extra pasta or meat dishes.
The only common complaint is the difficulty of securing a reservation, as seats often book out months in advance. Diners should also note that the omakase course is very substantial, and prices are in the premium range, as expected for this level of cooking.
Despite the high price point, reviewers consistently judge Sanwa to be excellent value. Recent guest reports from 2024–2026 place the set course between ¥19,900 and ¥22,000, plus a service charge. Optional add-ons quoted by diners include a karasumi spaghetti for ¥1,210 or a sea urchin peperoncino for ¥1,320. A glass of wine was recently reported at around ¥1,030–¥1,100.
