I’m a big fan of farmers markets the ability to get great tasting healthy items while supporting local farmers is a good thing. Anaheim does have its own farmers market every Thursday at Center Street Promenade and Center Street between 11 am and 3pm.
The farmers market is put on by the Downtown Anaheim Association with a nice thing if you are visiting is you can get 2 Hours Free in Parking Structure 3 (Oak & Anaheim) if you have a your ticket and get it validated. Like all farmers markets the vendors can ebb and flow but usually include a good selection of fruit and vegetables, citrus, various agricultural items as well as craft booths and dining booths.
