I'm curious if hounds have tried Sequoia Sake Brewery, SF - their website said they offer sake flight tasting (Nama/Genshu/Nigori) for $10; Your choice of sake $8 every Sat 12-6. Think they have tours too.
They also sell at restaurants & stores. I don't think I've tried them so would like to hear what others think of them.
