Bucks Fizz is a waste of good champagne.
There are places around here that sell most of those types of meat, mentioned in the op. They're incredibly expensive. Prohibitively so in most cases. In particular, I don't understand why the rabbit is so expensive. You can go west of the coast about 100km and shoot as many as you like of the little suckers for nothing more than the cost of a .22 bullet. You can even use a crossbow if you want.
Just don't let the cops catch you.
