I enjoy the farmers' market. Its nice to buy foods directly from the farmers.
I agree, its the best place for organic fruits and they're cheap as well!
Farmers' market
A farmers' market is a physical retail marketplace intended to sell foods directly by farmers to consumers. Farmers' markets may be indoors or outdoors and typically consist of booths, tables or stands where farmers sell their homegrown produce, live animals and plants, and sometimes prepared foods and beverages. Farmers' markets exist in many countries worldwide and reflect the local culture and economy. The size of the market may be just a few stalls or it may be as large as several city blocks. Due to their
young Mexican families to find affordable housing. 
Every Wednesday the Ajijic Tianguis (Farmers Market) attracts locals and expats alike. Several dozen vendors sell a wide range of products: fruits and vegetables, fish, chicken, prepared foods, clothing, jewelry, watches, electronics, arts and crafts, as well as used goods. In addition, there are organic farmer's markets which tend to attract more expats. 
Ajijic is a very festive village with many holidays, special events and parades about once a month. Mexico
