Addendum
Addendum occupies a low-key outdoor space behind Ad Hoc on Washington Street, positioning it as the casual, barbecue-focused sibling in Thomas Keller's Yountville portfolio. Where Ad Hoc serves family-style comfort food, Addendum leans into smoked meats and market-driven sides in a walk-up, counter-service format. For visitors tracking Napa Valley's farm-to-table sourcing culture, it represents one of the more direct expressions of that tradition in the valley.

A Counter in the Shadow of Something Bigger
Washington Street in Yountville carries a particular kind of culinary weight. Within a few hundred meters, you pass the premises of The French Laundry in Napa, and the broader cluster of dining rooms that have made this small town a reference point for serious eaters across the West Coast. Addendum sits behind Ad Hoc at 6476 Washington Street, occupying an outdoor space that reads almost defiantly unpretentious against that backdrop. There are no white tablecloths here, no tasting menus priced for expense accounts. What you get instead is a counter-service format built around smoked meats and seasonal sides, operating in a format closer to a well-sourced backyard operation than a destination restaurant.
That contrast is the point. Napa Valley's dining scene has long operated in two distinct registers: the formal, reservation-heavy rooms that draw international travelers, and a smaller tier of casual formats that serve the same geography with considerably less ceremony. Addendum belongs firmly to the second category, and understanding why that matters requires looking at where its food comes from rather than how it is served.
Sourcing as the Organizing Principle
The farm-to-table framework has been invoked so frequently across American dining that it risks meaning nothing. In Yountville, however, the infrastructure exists to make the claim verifiable. The Keller organization has cultivated supplier relationships across the Napa and Sonoma region over decades, and those networks extend to Addendum's kitchen even in its more relaxed format. The valley's position within Northern California's agricultural corridor gives any operation drawing on it access to stone fruits, brassicas, root vegetables, and heritage-breed proteins at a proximity that restaurants in urban centers spend considerably more to approximate.
Counter-service barbecue formats in this sourcing tier occupy a distinct position in American dining. Operations like Blue Hill at Stone Barns in Tarrytown and Single Thread Farm in Healdsburg have made farm integration a centerpiece of their identity, but they do so through highly structured, high-cost formats. Addendum represents a different application of the same sourcing logic: a format where the price of entry is low enough that the provenance argument can reach a broader audience. That is not a minor distinction. Much of American farm-to-table culture has become self-selecting, accessible primarily to diners already operating at a certain price tier. A walk-up counter that draws on the same regional agriculture as its fine-dining neighbors reframes that argument.
Where It Sits in the Yountville Picture
Yountville's restaurant density relative to its population is unusual by any measure. A town of roughly three thousand permanent residents supports a dining scene that draws visitors from San Francisco, the broader Bay Area, and international markets. The result is a range of formats operating simultaneously: the white-tablecloth rooms, the wine-bar adjacents, and the casual mid-tier that includes spots like Bistro Jeanty, La Calenda, and Bottega Napa Valley. Addendum competes in neither the formal nor the bistro tier. Its counter-service structure, outdoor setting, and barbecue focus place it in a narrower category that has few direct peers in the immediate area.
For visitors building a multi-day Yountville itinerary, Addendum functions as a useful counterweight to the rooms that require advance planning and significant per-head spend. Options like Lucy Restaurant & Bar and R+D Kitchen offer their own takes on the valley's casual register, but neither lands in quite the same format category. The broader Yountville restaurants guide maps the wider range if you are calibrating across a longer stay.
The Broader American Barbecue-Fine Dining Overlap
The overlap between serious sourcing culture and barbecue technique has become a recognizable strand in American cooking over the past decade. Operations informed by fine-dining discipline but expressed through smoked formats have appeared across the country, drawing on the same impulse that produced Smyth in Chicago and, in a different register, the sourcing commitments visible at Providence in Los Angeles. The argument in each case is that technique and provenance matter regardless of formality level. Smoke as a cooking medium is no less demanding in its execution because the result is served at a picnic table rather than on fine china.
Globally, the farm-integration model has found expression across very different formats. Atelier Moessmer Norbert Niederkofler in Brunico has built an entire culinary identity around alpine terroir and hyper-local sourcing at the fine-dining level. Addison in San Diego and The Inn at Little Washington in Washington represent the formal American version of that commitment. Addendum sits at the opposite end of the format spectrum while drawing on the same underlying logic. The sourcing argument does not require white tablecloths to be coherent.
Planning a Visit
Addendum operates on a lunch schedule on limited days of the week. The counter-service format means no reservation is required. Addendum absorbs the spontaneous visit without friction.
The outdoor setting means weather is a variable. Napa Valley's dry season runs from late spring through early fall, and that window aligns well with the format. Arriving early can help with menu availability. For travelers already in the valley for wine visits, the location on Washington Street makes it an efficient stop before or after a tasting room circuit. The format also suits the kind of casual mid-day meal that breaks up an itinerary built around more formal evening dining elsewhere, whether at the higher-register rooms in town or further afield at Lazy Bear in San Francisco, Emeril's in New Orleans, or Atomix in New York City.
