I have it on good authority that Bacchus Wine and Sake Bar (1954 Hyde St. at Union), i.e. the shoebox-sized pre-Sushi Groove drink-while-you-wait spot, has had a change of ownership. I’m not sure whether the contemporary speakeasy, which has only six bar seats, no website, and not even a sign, will remain as is or change form or name. But if it does, I will venture to guess that few will notice. Hopefully, though, the wine will keep flowing and there will be good things to come. I don’t make reservations, and I’ve usually got time to kill before I get my Sushi Groove on.
