Hidden behind a door in what was once a private dining room at The Matheson in downtown Healdsburg sits a restaurant within a restaurant.

It is all of 10 seats, situated around a u-shaped sushi bar, behind which three chefs slice, form, dollop, and blow-torch seafood into precious morsels of nigiri.

We’ve all had sushi that’s been decimated by cream cheese, mayonnaise, and gloppy sweet sauces. Sushi by Scratch is not that, even if the pristine fish does get finished with what at first may seem unlikely adornments. Instead, the effect here is far more finessed.

Opened in December, this is the first location of the reservation-only, omakase restaurant that started in Los Angeles in 2017 and has quickly spread to include outposts around the country, as well as in Montreal. Chef Philip Frankland Lee, who competed on “Top Chef” and his wife, Pastry Chef Margarita Kallas-Lee, founded the restaurant. A favorite of a bevy of celebrities, it held a Michelin star in 2021 and 2022.

I had a chance to try the experience last week, when I was invited in as a guest of Sushi by Scratch.

Dinner is 17 courses of nigiri at $185 per person. A word to the wise when booking: You will note that the reservation invites you to arrive 30 minutes before your scheduled reservation for a complimentary welcome cocktail.
