This could also be a case of them doing a bit...and just *acting* like they were calling a Chinese Restaurant. (see: Bob & Tom's "GODZIRRRRA! AHHHH!" moments when a Japanese caller calls in whenever Godzilla is brought up...then when Bob and or Tom say "Godzilla" the caller (along with a giant group in the background) screams in horror).
If that's the case, then...again...fuck the complaints. There's like 20 radio stations in New York. I'm sure you can find another one to listen to.
I know, people will say "that's not a valid argument", but it is. If you don't like what someone is doing, ignore it. There's enough psychotic people in the world that most radio shows that exist in that format aren't going to lose a ton of listeners over something like this. Anyone that's a fan of it isn't going to be bothered by it, usually, so that means that whomever complained probably...PROBABLY...was not part of the fanbase.
