Bisou Bistro (2367 Market Street) in the Castro is closed through January 9 for renovations and a brief vacation. The sudden closure was announced only on Facebook, and seems to stem in part from a death the post refers to "prayers for a little angel that just left us." We're still awaiting clarification on that, but it's sad in any case. The staff is taking a week off, and renovations were in fact occurring as of last night. They will reopen on Friday, January 10.
