I am headed to a conference at the Hilton San Francisco in/near Union Square this weekend. I have never been to San Francisco and am completely clueless of its geography, so please humor me in selecting a nice restaurant near the area (a walk or quick cab ride) for a few of my authors, etc. The meals will be expensed, but I really can't be over-the-top expensive. I was hoping to keep each person (including wine) to $50-$75. For lunch I was thinking somewhere in the area of $20 per person.
I would prefer Italian, French, or American, but any suggestions with great food and a more upscale (but not downright pretentious) setting would be appreciated.
Many thanks for the tips. If the suggestions are discussed more in length down below, just let me know.
