The new-ish Union St mainstay's unveiling its sweet rear lounge, a dimly lit drinker's den featuring sauna-like wood paneling, luxurious leather booths, a communal table, and a sweet model of the Golden Gate Bridge wrought from wood and metal cable that glows before a blown-up photo of the Bay at dusk, and features blinking fog lights on its towers and an asphault road surface for your drink -- totally setting you up to make "when's the party jumping off" jokes. All. Night. Long.
