Beware of dirty tricks!
I used to eat here frequently. However, my last two visits were terrible. The restaurant substituted a $14 fish dish for a $26 fish, without informing us. They simply served it. The first time I was not sure. The second time I asked and pointed out that it is a different kind of fish. They said they ran out of the fish I ordered, and reimbursed the price difference. But apparently they would just keep the overcharge if I had acquiesced.
And of course I am expected to be happy with a fish I haven't even ordered.
Make sure you're eating THE fish you ordered (not some cheap substitute) if you go to Mandarin Wok.
