I'll be honest, this is a dish that my Mom makes, and I never order it when I go out because my Mom's is that good (she uses filet for the beef). But there's only a few places that cook it well...and I find that the Bo 7 Mon (7 courses of beef) restaurants do a pretty good job.
Hong An Bo 7 Mon Restaurant (tender, juicy, and cooked perfectly)
9862 Westminster Ave Ste B
Garden Grove, CA 92844
Pagolac Restaurant (the most famous of the Bo 7 Mon restaurants)
14580 Brookhurst St
Westminster, CA 92683
Please let me know what you think if you try these places.
