In the vein of Chandavkl style reporting...
Was at Cupertino Village the other day and saw Guan Dong House. Then noticed they changed their Chinese name. The sure fire character "Xiang" 湘 meant they morphed into Hunan. Chinese name before the changed was indeed Guan Dong (which referenced NE/Dongbei style food). Still called Guan Dong House in English.
Grabbed a takeout menu to peruse, but don't have it with me now. It appears that they relocated from Fremont (or are opening up a new location).
Also, Szechwan Era nearby has the Chinese characters "Yunan Crossing Bridge Noodles" plastered on the window.
