I am not familiar with San Francisco at all but will be celebrating a loved one's birthday there. I'm looking for a restaurant with great food and wine. Not too upscale as this loved one doesn't like to dress up. I'm thinking more like business casual/smart casual. Price is not an option. But proximity is. The closer to Union Square the better. I've heard of Fleur de Lys and Masa? Of the two which one is better or does anyone have another suggestion. Thanks for the help.
