Hello Costa Women especially Madrid members. I’m new to the club but not new to Spain!
Just learned about a new farmer’s market in the main square of Matadero cultural center (metro Legazpi, just off south end of Madrid Rio park). First edition is next weekend, Sept 27-28, supposedly it will be every third weekend in the month. more info at http://mercadoproductores.es/ And a reminder (or maybe new news for some): the first Saturday farmers’ market in the Casa de Campo (metro Lago) is truly fabulous, you can get veges, fruit, cheese, sausage, fresh meat, olive oil, bread, wine and more, often sampling first (always nice, always fun 
).
