Visiting for weekend, looking for redtaurant for really good gumbo

Thanks. I'm actually within walking distance of this place.

Will be in a greens cookoff in Napa and need to purchase smoked meats (pork, turkey, etc.) to season the greens. Any recommended spots in/near Napa to purchase?

Headed to Napa for long weekend trip. Looking for a spot for lunch in San Fran that is on the route from airport to Napa.
