The Gilbert Farmer's Market has been great!
The market is right in Downtown Gilbert which makes it a great place to go to after breakfast and Liberty Market. We've always had a great experience with the vendors and really like visiting One Windmill Farms while we are there (they seem to have the largest selection of fresh veggies available).
The market is outdoors which can get pretty hot in the summertime (but is absolutely perfect any other time of the year) but since it is in a parking lot with covered parking, all of the vendors are in the shade and you don't need to stand in the sun the whole time.
Lots of vendors are available there and (thankfully) very few are art vendors - most are selling food (which is why I go in the first place). There are groups selling bread, ready to boil pasta, jellies and jams (my favorite is the pineapple jalapeno), plenty of fresh vegetables, fish, and beef.
There are usually one or two food truck in the area and some live music. I would really like to see more food trucks in the future, but I love a good food truck gathering.
Most of the vendors take credit cards through their square readers on their phones which is convenient.
