$30 per is a great price for that wine.
Julia is at the corner of Sutter and Steiner. Reservations are a must. The top of Nob Hill is about 15 blocks away.
If you are staying in Nob Hill and you want a top of the line dining experience while staying in Nob Hill then I strongly recommend Charles Nob Hill at the corner of Jones and Clay. Reservations are basically essential.
