We just got word that there is a rather large roaring in the financial district. Or, as our tipster informed us, there's a "[b]ig ass fire in the Financh right now." Oh dear. "Sirens everywhere, smoke smellable all over Embarcadero Center," we're told

We'll update as soon as we know more.

Update11:15 a.m.: This is HORRIBLE. Though unconfirmed, we have word (and photo) that the fire might be coming from Perbacco.

Update 11:30 a.m..: It is might be happening at Perbacco. How terrible. Word is Umberto Gibin, owner of Perbacco, is standing next to the firetrucks and hoses. It's a horrible scene outside, we're told. No word of any injuries.

Update 11:37 a.m.: SFist reader Taylor Pipes tells us, "a building engineer observing outside was telling me the fire / smoke appeared to be coming out of a grease trap piping system causing a lot of smoke."

Update 11:46 a.m.: Tadich Grill it is! Appeal and BCN report that it's Tadich Grill.

Pipes tells us that, thank god, Perbacco is still open today. "Perbacco has a sign saying open for biz today...police tape around Tadich Grill storefront," we're told.

Update 11:58 a.m.: "Cable cars on the California line cable cars. Shuttle buses are picking up the slack," says Appeal.

Update 12:20 p.m.: San Francisco's "oldest restaurant" has been "severely damaged," reports CBS 5. Also, the fire, which started in a flue, is now out and cable cars are running again. Yay.
