The is one in Epsom on the first Sunday of each month. There is a fabulous veg stall. They come up from Kent and the produce is excellent. We always buy loads of carrots, greens, celery, kale, parsley and fruit. Most of it is for the animals, we get through a lot of veg with them. It is very reasonable, and we never spend more than £10 for a huge bag of veg.
There is also a lovely cake stall, jam, lavender, plants, bread and loads of dead things, which we don't need being veggie.
We always meet up with a friend, and then go for coffee and hot fruit toast in one of the cafes.
