From the Health Department:
Mission Chinese was closed by the Department of Health because of a public health hazard that could not be corrected at the time of the inspection. In this case, the restaurant had a severe mouse infestation that required professional pest control services.
Eater points out a sign in the restaurant's window that reads "Closed because of leak in basement." Is that a euphemism for mouse tsunami? We reached out the restaurant for an explanation but nobody picked up.
The restaurant received an A on its last inspection in March and with any luck will have foodiots lining up in no time. Try the lamb!
