Belgium is a coastal country, with lots of seafood available, fresh. It is a land of French cuisine in the restaurants, without the French wait staff or attitude. And it is very, very easy for me as a low carb adherent to eat, even when I am on the road and have to eat out all the time. But it is even better when I can cook on my own.
The supermarkets sell all sorts of things, such as lamb, rabbit, duck, wild boar, and on the shelves it is easy to find offal (kidneys, heart, liver, brains, etc.). The eggs are almost all from free range chickens and some say, even on the box, that they don't throw your omega 3s and 6s out of balance. You can buy cheeses made from raw, unpasteurized milk, as well as yogurt, which is simply divine. And the selection of cheeses is enormous! The dark chocolate here is better, and a whole lot less expensive, than what we have to make do with in the states. But even better are the fresh food markets on the weekend.
The one in Antwerp is simply not to be missed. The quality of the vegetables, fruit, cheeses, butter, fish, meats, olives, olive oil, etc. is just amazing. I enjoy wandering around the market on Saturday morning and seeing all of the high quality food. Serious cooks know to get the best produce, fruits, and meat at the markets.
