If you are heading down the A 10 on the way to Dover , stop at Braughing, just south of Roystan. The butcher in the village makes IMHO the best sausages in the south. No fancy ingrediants, just top quality. Best to stick to normal size ones, receipe doesn't work quite so well with chipolatas.
I find the sausages served on the inner side of Tertre Rouge quite delicious, with a bit of mustard, mmhhhhh. :D
