I'm a Philadelphia chowhound in downtown SF for a conference in early October. I'm looking for a place with a lounge/bar to sample different types of sake, for a few beginner/intermediates including myself. Best would be a place with a sake 'menu' with types, descriptions and maybe even flights/samplers. Or a place with helpful and patient staff. We don't want a place where we're expected to buy dinner, hence the bar/lounge rather than a pure restaurant with an exhaustive sake list.
All help appreciated! It was great to read the 'joy of sake' post.
