I'm catering for my family for Christmas in Paris in a few weeks. There's six of us and we're looking to do a nice Christmas lunch/dinner at home. I was just wondering if anyone knew of anywhere where I could buy a high-quality pre-cooked Turkey such that I only needed to make some gravy and other accompaniments the next day? Failing that, is there anywhere that people recommend to buy:
a) Oysters that are already shucked (on Christmas eve, for eating on Christmas day)
b) A leg of ham for glazing
c) A decent Buche de Noel
Keen for suggestions!
