Orphan's Toys
It wasn’t bugged for me. Notice, the grawl indicates the day of the week, and resets (I am guessing) at some time other than reset. Perhaps it is midnight PST? His dialog did not change at reset, I had to wait until 24 hours after I first spoke to him (or so).
My clue said the chef was somewhere made with flowers (The Grove). The other option (previous day for me) is a popular dish that charr find nice (Black Citadel).
I’m guessing he might also reference whatever race the character that first speaks to him happens to be. (Not sure about that.)
