Every bar has that special place in the back. Best seat in the house when you really want to get situated and make your night happen.But not every bar has this kind of special place in the back...Make your way through Liquid Gold, a sleek new beer-and-wine bar with a shop in the back for all your “I need more good beer to take back to my place with my new friend here” needs—it’s opening Saturday in Nob Hill.You’ll see. It’s a great neighborhood spot, sure. Feels that way right when you walk in. ( Here’s the sample menu and the slideshow .) You generally feel pretty welcomed by 30 beers on tap (mostly local), a few more taps of wine and a 35-foot bar with hints of gold in it. They’ve got a few screens, too, so it works for an easy World Series–related pit stop.If it just stopped there, you probably wouldn’t have any complaints.But behind all that is the leather sofa, the big lacquered communal table, the shelves of wine and the five refrigerators full of beer. Buy whatever you need.And whatever you don’t.
