I had posted to ask for a good place for an excellent meal, dining alone, in SF, and had been steered to Atelier Crenn. I went last night, and wanted to thank the recommenders, as well as to offer my quick thoughts.
First, my server made excellent suggestions and did not flinch at a half-full table, make a lot of awkward small talk, or hustle me along (things I occasionally encounter when dining alone). The chef emerged from the kitchen a few times to check on things. I had the four-course tasting menu with wine pairings, which was a fairly sizable amount of food. I started with the potato, and then moved to the foie gras ($10 supplement), the duck, and the chocolate mousse/pear dessert. A few extra dishes appeared as well; a frozen pea soup, a mushroom broth, a cilantro palate-cleaner, etc.
I thought the foie was the best dish and well worth the supplement (it was one of the server's recommendations). Of all things, I have to also highly praise the wine pairings; the sommelier did an excellent job, and I also appreciated that (as the wine came out well in advance of each course) they made certain I had wine left when my dish would actually arrive. I thought the only thing that didn't work was the mushroom broth -- it didn't have a lot of flavor, although in full disclosure I admit that I am not a soup person -- but since it was an extra, I feel a bit guilty mentioning it.
Overall, a really great experience, and I will direct others this way.
