What do you mean by "sickness" ? DId you mean duck, and it autocorrected to sickness?
As was said, duck is sort of liek dark meat turkey or chicken - i.e. it actualy has flavor.
The duck at Chefs is confit, which means it has been stored in duck fat, which means it is supposed to be very moist. I have had it a number of times, and so has my daughert (she loves duck). Most of the time it is good, as
@Rogue21 said, it has been dry a few times, but not often. Maybe it sat in the pass for too long under heat lamps, that restaurant seems to be very busy all the time.
The sauce is a pan sauce with dark cherries. If I had to guess how they make it, I would say they cook the duck, then deglaze the pan with something, maybe duck stock, more likely chikcken stock, and then add the cherries, reduce, then mount the sauce with butter to finish. I havent had the dish in a while, so any sort of herbs escapes me.
