A sign on the door of Dancing Pig BBQ (544 Castro Street), which closed abruptly and without explanation last week, now proclaims, "We are making improvements!" The trouble is, restaurants don’t just go dark like this unless something is up. More curiously, the owners appear to have to reapply for their liquor license for the space, and that application just went in on Friday. Stay tuned for more on this developing situation as we learn it, and as always, the Castro needs all the food improvement it can get. [Earlier] Update: Nope. It looks like the guys from Poesia are taking it.
