Saigon Grill
Saigon Grill was a Vietnamese restaurant on Amsterdam Avenue at 90th St. Thus, it was not strictly in Morningside Heights, but it did normally deliver to the area. It closed in 2014.
The restaurant suspended its delivery service due to an ongoing labor dispute. The workers were paid under minimum wage and were instructed to work in conditions that are alleged to have been unsafe.
Apparently, the downtown location, Saigon Market, on University Place near NYU, is much swankier. But it's still owned by the same immoral owners.
