Origin'O

Some vegan cheeses, vegan yoghurt, many kinds of vegan milk (soy, rice, hazelnut, oat, spelt...), vegan spreads and traditional faux meat (traditional in the sense that it doesn't taste or look like meat all that much), clearly marked vegan pies and deli, and lots of other organic products such as fruit and vegetables, cornflakes, body lotions etc etc.

Also has a selection of organic Japanese products such as Japanese tea, seaweed and umeboshi (pickled plums).

Rather expensive but it's organic so hey.

Nice Bio shop in Leuven. Much more health oriented that the commercial Bio Planet (Colryut group). Good selection of products, nice service.

The employers here are always willing to give you a friendly advice. It's a relative small shop but it has a good range of products. Very good central location.

This is a small shop, just outside the city center. I walked past it the first couple of times until I recognized the logo and decided to have a look

The shop sells good fair trade, organic and vegan supplies. It was very expensive though, I don't come there regularly. I just don't have that kind of money. Nonetheless, I liked the shop, though it really is very small and a lot of favorite vegetarian things, just weren't there. Furthermore

I recommend having a look at the meat alternatives which are juist great!

Sadly this shop sells meat, which I find very unnecessary. This spoils what is otherwise a reasonable choice.
