[quote. Also, as much as you could say this about any city, is SF considered a more or less formal type of place when it comes to business (medical field)? Thanks and I look forward to meeting some igents soon.[/quote]
SF is an extremely casual city. I typically where a suit or odd jacket/trousers & tie to work and I rarely see more than a dozen men wearing coat and tie on any given day.
There is a garage just around the corner from Wingtip on Clay after Montgomery and another on Pine between Montgomery & Kearney (a couple of blocks from Wingtip). I'd call Wingtip and ask them for recommendations.
