I haven't seen roasted duck there but I'm sure you will find frozen duck in the store.
No roasted duck. Sorry. Get the frozen one and just put it in the oven
No roasted duck. But you do get whole duck
They do not have them already roasted, but they do have frozen whole ducks which one can roast.
Haven't seen any there. Might want to ask your favorite Chinese restaurant to do a special for you.
