The Old Mandarin in sunset district 40th and Vicente.
A must try was the Beijing style Lamb hot pot, razor thin slices of lamb, special dipping sauce shipped from beijing.
another must try was the fried beef patty panckaes, multi-layer pancake with ground beef in between, q bit oily/greasy, but it is very tasty.
The house special sauce is also for sale $1.50 per serving. The meal a bit expensive, two people with no alcohol, was close to $40.00, and we were not overly stuffed. but the quality of foods was good.
Recommended this restaurant if you like Lamb or beef hot pot, the special sauce is just worth a visit. (My guess is a combination of seasame paste, salt, celantro, and chinese herbs spices.
