Seems like months ago Melanie Wong wrote a little paean to their excellence, so when I was there shortly after I asked about them. The waiter claimed no knowledge of their existence, and tried to steer me to Manila clams in black bean sauce. I'm hoping to go there Thurs. night for a sedate birthday dinner and thought I might try again. Is it a seasonal thing? Was the waiter trying to save them all for himself? They sure looked good in the picture(which I showed the waiter to no avail, still total denial). What is the Chinese name? Any advice appreciated.
