I had thought that your original request was for DINNER items available for takeout - prepared dinner you can pick up and have with some wine. Dinner without cooking. Danish from Model bakery or a tuna burger from Gotts is not going to do that. The description of Roadhouse sounds perfect, if they get that order in/takeout service available.
Not sure what time it closes, but part of the Oxbow extension is the Fatted Calf. Porchetta, soups, salads…meal items cooked and at the ready. Reheat at your house and enjoy.
Or at Tra Vigne pizzeria in St. Helena, take out a good sized order of meatballs in sauce and cook your pasta, reheat the meatballs, and you have the start of a meal. You can also take out salads there - just have the dressing on the side for when you are ready to dress your salad and eat.
