Haven't seen this posted yet, but I was grabbing some take out from Lotus Chinese Cuisine on Sepulveda Boulevard in Culver City (right at the 405 ramp), and I noticed the sign in the parking lot said "Oriental Seafood Inn - Parking". It looked like the exact same sign from the parking lot behind the now-closed Oriental Seafood Inn in Venice/MDR.
So of course I asked the woman inside and she confirmed that yes, this is the now the same restaurant that was on Lincoln Boulevard in Marina del Rey. They must have taken over the Culver City Lotus branch, for the menu has changed to that of a seafood house, and the place has been remodeled complete with live lobster tanks.
As far as I know, this has nothing to do with the Lotus branch in Santa Monica, which has been under different ownership from the Culver City one for quite some time.
