In Veyrier (Geneva, Switzerland) we are very lucky to have three fruit and vegetable markets a week; on Wednesdays, Thursdays and Saturdays in different spots around the commune.
My favorite one is a farmer's market situated in a barn in the middle of the greenhouse area in Les Marais de Troinex.
There, you can find a smallish, yet nice array of vegetables, fruits, homemade jams, great artisan cheeses as well meat from the Jura region (beef, sausages, porc...). There you even have the possibility to sit down at a wooden picnic table and enjoy a cup of tea with a slice of cake or tart...
A cute and practical little market that offers good products (mostly regional or Swiss) for a reasonable price!
