Osteria da K. [káppa]

Broth first, then the fish

A kombu-enriched acqua pazza sets the measure: broth held clear, seafood left legible. Andi Preuss, Executive Chef at Osteria da K. [káppa] in Tokyo, keeps that discipline close to the plate. His line runs through early service in Berlin, apprenticeship in Saxony, hotel cooking in Austria and Trout Point Lodge before his present work between this Ginza kitchen and Oxalis Restaurant in Dartmouth, Nova Scotia. The record matters because it reads as stations rather than résumé polish: intern, apprentice, chef, Executive Chef, each title earned in service. Preuss states the kitchen’s standard plainly, “If something is beautiful, but it tastes not good, then it’s not worth it.” At [káppa], that sentence suits the room. The restaurant opened on August 25, 2014, as an Italian seafood osteria run by Sushi Yoshitake, and its craft sits where Italian structure meets the handling instincts of Edomae sushi. Preuss’s role here is execution as much as authorship, keeping seafood ragù and kombu broth work direct, without letting technique get ahead of flavour.

Italian form, sushi-grade fish

The program is à la carte, built for a diner who might want sea urchin in pasta, Kinmedai or Nodoguro in acqua pazza, and abalone folded into ragù rather than presented as a trophy. The fish comes through channels associated with top sushi restaurants, including direct seasonal seafood from Yaizu Fishing Port, then moves into Italian forms: pasta, stew, ragù, broth. The method is not fusion as ornament. It is a set of decisions at the bench. Sea urchin needs enough fat and starch to carry it, not bury it. Kinmedai and Nodoguro need heat that firms the flesh while leaving the broth clean. Abalone can disappear into ragù and still change the dish. The kitchen’s link to Sushi Yoshitake gives the osteria its fish vocabulary, but the plate stays Italian in shape. Wine is part of the rhythm, curated to sit beside salinity, shellfish sweetness and the depth of kombu without turning the meal into ceremony.

A counter above Hanatsubaki Street

The room is narrow, intimate and quiet enough for the work to register. Counter seating makes the pass feel close, especially for solo diners coming through Ginza after service elsewhere or after work. The building sits along Hanatsubaki Street, near Shimbashi Station, with the restaurant upstairs rather than announced at street level. That position gives [káppa] its hideout quality without asking the room to perform mystery. The style is polished but relaxed: an Italian osteria scaled to Ginza, with seafood doing the formal work. Dishes arrive as part of a steady progression rather than a fixed tasting menu, and the room gives them enough space. The final memory is often not a grand plate, but a clear broth holding Nodoguro, kombu and the patience of Osteria da K. Osteria da K. [káppa] in Tokyo.
