Shandong House Restaurant at Geary and 2nd recently underwent a makeover and re-emerged as Xi'an Gourmet. Their chef is from Xi'an, so it was an easy enough transition.
I've been a big fan of Xi'an food since first visiting Xi'an Famous Foods in New York five years ago, so I rushed down there as soon as I heard about the metamorphosis. I wasn't disappointed by the lamb roujiamo or the you po mian, the only two items I've tried so far. Next up, yangrou paomo, liang pi and saozi mian.
They've kept the Shandong dishes on the menu as well as the Chinese-American Golden Hits, so it's a big menu, but the Xi'an dishes can be found primarily under "House Special" and (partly) the "Hand Pull Noodle" sections.
I'ts great to have another regional Chinese food option in a convenient SF location, especially one as tasty as Xi'an cuisine.
